This invention relates to toys.

More particularly, the invention relates to a toy for an animal.

In a further respect, the invention relates to an animal toy which when thrown can bounce erratically, which minimizes the probability of harm to an animal trying to catch a toy which has been thrown, which is symmetrical but is shaped to include points at varying distances away from the center of the toy to enable the toy to bounce erratically, which is permanently sealed so that the toy repeatedly compressively elastically deforms and bends in the same predictable manner, which includes a soft fabric outer surface that compresses to absorb blows and soften the impact when the toy hits an animal or other surface, and which can withstand being bitten or chewed by a dog and continue to function.

A wide variety of animal toys are known. One kind of toy is made of hard rubber and comes in a variety of shapes. For example, a dog bone made of hard, tough rubber has long been sold in retail outlets. A hard, tough rubber is utilized to make it difficult for a dog to chew through the bone. The rubber also adds weight to the toy, permitting the toy to be thrown long distances. Finally, the rubber material used to make the toy also enables the toy bone to bounce into the air. Dogs like chasing bouncing toys. While this type of toy is without question resistant to be damaged or chewed up, the toy is also dangerous. If the toy when thrown bounces into a dog, the toy can, due to its hardness, injure the animal. Worse, if the bone is thrown in the air and hits the dog straight away before the bone hits the ground, the dog can also be injured.

Animal toys can be constructed by attaching sections of felt fabric to the outer surface of a rubber shell such that the fabric sections are separated by a seam or strip of rubber or other polymer. In practice, the fabric sections are adhered or otherwise fastened to the rubber shell such that the edge of one piece of fabric is adjacent the edge of a second piece of fabric. The adjacent fabric edges define a rough seam line. A strip of rubber tape is attached to the pieces of fabric such that the tape covers the seam line. After the tape is attached, the entire rubber shell—fabric piece—rubber tape assembly is placed in a mold to melt and cure the rubber tape. A particular problem associated with this procedure is that the edges of the top and bottom portions of the mold tend to engage and stick to the rubber tape, pulling a large portion of the tape off the seam line.

One type of retrieval training toy comprises a piece of rope or cord attached to a plastic body or to a body comprises of a small canvas bag filled with a pliable material like sawdust, sand, small pieces of paper, etc. A trainer or other individual utilizes a retrieval toy by grasping the piece of rope and using the rope to throw the toy. The dog or other animal retrieving the toy takes the rope or body and carries the toy back to the trainer. These kinds of retrieval training toys ordinarily are not sealed or do not bounce

Accordingly, it would be highly desirable to provide an improved dog's toy which can be thrown a long distance to bounce in an erratic pattern liked by dogs while producing only a small risk that the toy will injure a dog. It would also be highly desirable to provide an improved method for molding a dog's toy to minimize the quantity of rubber tape pulled off the seam line of the toy during molding of the toy to soften and cure the rubber tape.

Therefore, it is a principal object of the instant invention to provide an improved toy.

A further object of the invention is to provide an improved animal toy which reduces the risk that the toy will, when thrown, injure an animal chasing the toy.

Another object of the invention is to provide an improved animal toy which elastically compresses and bends to minimize the risk of injury to an animal.

Still another object of the invention is to provide an improved method of producing an animal toy which reduces the likelihood that polymer seam tape will significantly damaged during molding.

Still a further object of the invention is to provide an improved retrieval toy which includes a throw-rope attached to a toy body, which is sealed, and which bounces.

Yet another object of the invention is to provide an improved method for manufacturing a pliable retrieval toy of the type including a throw-rope attached to a toy body.

Turning now to the drawings, which describe the presently preferred embodiments of the invention for the purpose of illustrating the practice thereof and not by way of limitation of the scope of the invention, and in which like characters refer to corresponding elements throughout the several views, FIG. 1 illustrates a toy including a hollow cylindrical rubber core 11. If desired, supporting walls can be formed inside of hollow core 11 much like bulkheads are formed inside the hollow hull of a ship. Pieces 12, 13 of felt or another desired fabric are adhesively secured or otherwise affixed to the outer cylindrical surface 28 of core 11. Fabric pieces 12, 13 are shaped and dimensioned and applied to surface 28 such that a space or groove of substantially constant width between the pieces 12, 13 is formed. This track is filled with an elastic rubber material to form strip 14. Alternatively, one or more fabric pieces can be utilizes to complete cover surface 28, after which a strip 14 of material can be attached on or in the fabric to form a strip 14 dividing the fabric into sections on either side of the strip 14. Strip 14 presently has a width in the range of one-sixteenth to seven-sixteenths (1.5 mm to 10.5 mm) of an inch, preferably one-sixteenth to five-sixteenths (1.5 mm to 7.5 mm) of an inch.

Cylindrical end piece 18 includes rubber piece 19 and fabric piece 20 adhesively secured or otherwise secured to piece 19. End piece 18 is secured to circular end surface or lip 22.

Cylindrical end piece 15 includes rubber piece 16 and fabric piece 17 adhesively secured or otherwise secured to piece 17. End piece 15 is secured to circular end surface or lip 21.

After end pieces 15 and 18 are secured to the ends of core 11, rubber pieces 19 and 16 and core 11 circumscribe and seal closed cylindrical volume 29.

The fabric used to cover surface 28 is presently preferably felt because felt provides a soft surface which reduces the strength of a blow to an animal when the toy inadvertently strikes an animal. Felt also resiliently compresses to absorb some of the force of the blow. While any felt can be utilized, the preferred felt comprises a firm woven cloth of wool or cotton heavily napped and shrunk to form a smooth resilient texture.

The core 11 of the toy of the invention must be fabricated from rubber because core 11 must be able to be elastically compressed. As used herein, the term rubber includes natural or synthetic rubbers and polymers or other components which produce materials having the properties of a rubber.

Since the wall of hollow core 11 must have “give”, it is important in the practice of the invention that the wall be relatively thin. The thickness, indicated by arrows A in FIG. 1, of the wall of core 11 is in the range of about one-sixteenth of an inch to five-sixteenths of an inch, preferably one-sixteenth of an inch to three-sixteenths of an inch.

At the same time, the rubber utilized to make core 11 must be relatively tough so that a dog or other animal cannot with its teeth readily puncture core 11.

Another important feature of the toy of the invention is that core 11 must sealingly circumscribe a gaseous volume 29. Volume 29 ordinarily is filled with air, but nitrogen or any other desired gas can be utilized. It is acceptable for the gas to have some moisture content; however, filling volume 29 with a fluid is not presently preferred because the fluid can add substantial weight to the toy and because the fluid does not compress as readily as a gas. After core 11 and end pieces 15 and 18 are assembled and sealingly enclose volume 29, additional gas can, if desired, be added to volume 29 to pressurize volume 29. Any desired method can be utilized to pressurize volume 29. For example, a composition can be put into volume 29 during manufacture. After member 11 and pieces 15 and 18 are assembled to sealingly enclose volume 29 and enclose the composition in volume 29, the assembled unit is heated to cause the composition to release gas to pressurize volume 29.

Pressurizing volume 29 is preferred because the pressure helps to support the wall of core 11 while still not preventing the wall of core 11 from being elastically compressed.

The center point 40 of the toy of FIG. 1 is circumscribed by and spaced apart from the cylindrical wall of core 11. Point 40 is also equidistant from each end piece 15, 18. The center point of a toy constructed in accordance with the invention is generally at an average distance from points; lines, or angle on the exterior of the toy. It is important that each toy include points on its exterior which are not equidistant from the center point of the toy. This construction insures that the toy will have the ability to bounce erratically. A toy with all surface points equidistant from the center of the toy is not utilized in the practice of the invention.

As earlier noted, elastic core 11 can be compressed, i.e., the cylindrical wall of core 11 can be elastically pushed inwardly. Another important feature which can be incorporated into toys constructed in accordance with the invention is that they can be bent. In FIG. 1 for example, after the toy is assembled, end piece 18 can be moved in the direction of arrow L simultaneously with the movement of end 15 in the direction of arrow M. When an object is bent, part of the object is subject to tensile forces while another opposed part of the object is subjected to compressive forces.

The hollow toy 25 illustrated in FIG. 2 includes a doughnut-shaped rubber core 26 which sealingly encloses gas-filled volume 40. Felt cloth 27 or other fabric substantially completely covers the outer surface of core 26 in the same manner that cloth pieces 12 and 13 cover substantially the entire outer surface 28 of the toy shown in FIG. 1. Cylindrical aperture 44 extends completely through toy 25. Knot 41 formed in rope 42 does not fit through aperture 25, which permits end 43 to be grasped manually so that the rope 42 and toy 25 can be twirled and thrown.

The toy 30 illustrated in FIG. 3 includes three hollow cylindrical legs 31, 32, 33 which co-terminate to form a three-legged toy. While the angles between legs can vary and the number of legs in the toy can vary, it is presently preferred that the legs 31 to 33 be normal to each other.

As used herein, when a toy is thrown “randomly”, the toy is thrown without any attempt to control the orientation of the toy in the air. When the toys illustrated in FIGS. 1 to 3 are thrown randomly, it is highly likely that they will bounce erratically when they hit the ground. It is possible, however, for each toy to be thrown so it will not bounce erratically. For example, as shown in FIG. 4, the toy in FIG. 1 can be thrown end-over-end toward the ground in the direction of arrow Y, hit the ground, and continue to travel in the direction of arrow D. This does not constitute an erratic bounce because after the toy hits the ground it continues to travel in the same direction D.

Similarly, it is possible to throw the toy of FIG. 2 like a frisbee, such that the toy 25 hits or lands on the ground flat on one of its two opposed circular faces and stops dead. This does not constitute an erratic bounce because the toy 25 does not bounce. Throwing the toy to accomplish such a landing is difficult at best. Alternately, toy 25 can be thrown in a vertical orientation which causes it to land on edge on the ground and roll in a straight line. This is difficult to accomplish on a consistent basis, especially if rope 42 is still in the toy 25 when it lands. To insure that rope 42 stays in the toy, a knot can also be formed in end 43 which will not pass through aperture 44.

Throwing toy 30 of FIG. 3 so that it will not bounce erratically is difficult. It is possible to throw toy 30 so that it will make a three-point landing with the distal end of each leg 31 to 33 hitting the ground simultaneously or almost simultaneously so that toy 30 hits the ground and stops dead. Such a three point landing is highly unlikely.

As used herein, a toy has an erratic bounce when, after it hits the ground, it moves in a direction different from the direction it was traveling just prior to hitting the ground.

One important reason why toys with an erratic bounce are critical in the practice of the invention is that when a toy makes an erratic bounce the speed of travel of the toy after the bounce appears less, sometimes significantly less, than if the toy continues in the same direction of travel after the toy bounces. Since a primary object of the invention is to minimize the risk of injury to an animal, it is imperative that a toy not continue going in the same direction like a freight train after it hits the ground, but that some of the inertia of the toy be consumed by insuring that the toy bounce erratically. The ability of the toy to be compressed and to be bent on contacting the ground also consumes some of the toy's inertia. An improved method for producing an animal toy is depicted in FIG. 5.

The method includes the step 50 of “mold top half and bottom half of toy”. If desired, methods other than molding can be utilized in step 50 to form the top and bottom halves of a toy.

Step 51 comprises “apply glue along seam edge of each half, press halves together along seam edges to form unitary member having a seam line, place halves in mold to heat and cure adhesive”. Fasteners or methods other than gluing can be utilized to fasten together the top and bottom halves along a seam line.

Step 52 comprises “apply rubber tape along seam line”. The tape can consist of any polymer or other material which is softened (by heating or any other desired method) and then hardens and cures.

Step 53 comprises “apply upper felt cover to top half of unitary member such that edge of felt cover overlaps rubber tape”.

Step 54 comprises “apply lower felt cover to bottom half of unitary member such that edge of lower cover overlaps rubber tape and opposes edge of upper felt cover”.

Step 55 comprises “place unitary member in mold to soften and cure rubber tape and to draw opposing edges of felt covers together”.

Additional features of the invention, along with the method of FIG. 5, are further illustrated in FIGS. 6 to 9. The toy illustrated in FIGS. 6 to 9 has the shape of a dog bone, but the shape and dimension of toys made in accordance with the invention can vary as desired.

Symmetrical hollow opposing halves 60 and 61 are illustrated in FIG. 6. Each half 60 and 61 is presently preferably molded from a rubber or polymer compound which, after being molded and cooled to ambient temperature (76 degrees F.) is bendable and resilient. The material and method utilized to manufacture each half can vary as desired.

Halve 60 includes generally flat upper area 64, front side 75, back side 74, inner surface 72, and edge 65. Arcuate edge 67 extends around halve 60. Halve 61 includes generally flat lower area 71, front side 76, back side 73, inner surface 63, and edge 62. Arcuate edge 70 extends around halve 61. Edge 62 opposes and has a shape, contour and dimension equivalent to the shape and dimension of edge 65.

Line of weakening or groove 85 extends along the inside of arcuate edge 67. Line of weakening or groove 86 extends along the inside of arcuate edge 70. Lines of weakening 85, 86 are important in the practice of one embodiment of the invention because they function to require less pressure be applied to deform edges 67 and 70, respectively, (and the felt covering edges 67 and 70) inwardly or outwardly. When less force or pressure is required to deform edges 67 and 70, it is less likely that edges 67 and 70 will cause injury when a toy constructed in accordance with the invention strikes an animal or human being. The lines of weakening can be formed in any desired manner. For example, instead of grooves 85, 86, perforations can be formed through edges 67 and 70 to remove material from and weaken edges 67 and 70. The lines of weakening can be formed on the inside of arcuate edges 67 and 70, on the outside of arcuate edges 67 and 70, through edges 67 and 70, etc.

The radius of curvature 66 of edges 67 and 70 can vary as desired. The radius of curvature of the edges of a toy which are on the outer surface of a toy and can contact the body of an animal or human being is, however, preferably ¾ of an inch or greater. A larger radius of curvature makes it less likely that an edge 67, 70 will penetrate and injure an eye or other part of the body of an animal or human being.

FIG. 7 also illustrates the top 60 and bottom 61 halves. In addition, dashed lines 77 in FIG. 7 illustrate adhesive which is placed on edge 62, and if desired on edge 65, to glue together halves 60 and 61 to form the seam line 79 illustrated in FIG. 8. After halves 60 and 61 are glued or otherwise fastened together, a strip of polymer or rubber is wrapped around and covers seam line 79. The polymer strip is indicated by dashed line 78 in FIG. 8. The polymer strip 78 can be sticky and adhere by itself to tops 60 and 61. Or, adhesive can be utilized to adhere strip 78 to tops 60 and 61. Or, some of the adhesive used to adhere the halves 60 and 61 may ooze out from seam line 79 and be used to adhere strip 78 to halves 60 and 61 over seam line 79. If desired, polymer strip 78 can be omitted.

Once strip 78 is fastened over seam line 79, a felt cover, indicated by dashed line 80 in FIG. 8 is placed over halve 60 such that edge 82 overlaps strip 78. A felt cover, indicated by dashed line 81 in FIG. 8 is placed over halve 61 such that edge 83 overlaps strip 78. Edges 82 and 83 are spaced apart as shown in FIG. 8. An adhesive (not shown) can be applied to covers 80, 81 or to halves 60, 61 to facilitate the adhering of the covers 80, 81 to the halves 60, 61.

Once the strip 78 and covers 80 and 81 are applied, the halves 60 and 61 are placed in a mold 88, 89. One or more mold parts 88 and 89 are moved to compress halves 60, 61 and covers 80, 81 in the directions indicated by arrows 100 and 101. Mold edges 92 to 95 engage edges 82 and 83 to stretch edges 82 and 83 toward one another in the directions indicated by arrows 96 and 97 in FIG. 9. Mold 88, 89 heats, softens, and cures the polymer or rubber in strip 78. Mold edges 92 to 95 also compress edges 82, 83 inwardly against strip 78 to facilitate the adhering of edges 92 and 95 to strip 78 when strip 78 softens. The mold 88, 89 also heats felt covers 80 and 81 to facilitate adherence of the covers 80 and 81 to halves 60 and 61. If strip 78 is omitted, mold edges 88, 89 compress opposing edges 82, 83 toward each other, preferably so the opposing edges abut.

Another method for applying rubber or polymer, either in place of or in conjunction with strip 78, is to prepare a stack of felt covers 80 and/or 81. The number of covers in the stack(s) can vary as desired, but presently there are about fifty covers in a stack. The edges of the covers in each stack collectively form the sides of the stack. Latex or another synthetic or natural rubber or polymer mixture is slathered or brushed onto the sides of the stack, i.e. is applied to the edges of the covers in the stack. The viscosity of the latex or other polymer mixture can vary as desired, but the mixture presently has a viscosity similar to that of honey. Covers 80 and 81 are peeled off each stack and applied to halves 60, 61. The mold edges 92 to 95 engage the edges 82 and 83 to stretch edges 82 and 83 toward one another in the directions indicated by arrows 96 and 97 in FIG. 9. Mold 88, 89 heats and cures the polymer or rubber that was applied to the edges of covers 80 and 81 while the covers were in a stack(s). Mold edges 92 to 95 compress edges 82, 83 inwardly toward one another. The polymer or rubber that was slathered on the edges 82, 83 functions to hold and seal edges 82, 83 adjacent one another.

The thickness, indicated by arrows T1, of the wall of halves 60 and 61 with respect to the thickness, indicated by arrows T2, of the felt covers 80, 81 is important in one embodiment of the invention. Many dog toys utilize heavy, thick, relatively hard rubber, probably with the intent of making it difficult for a dog to chew up the toy. Such rubber can, however, turn the toy into a dangerous projectile when the toy is thrown. I have discovered that utilizing a felt cover with a thickness in the range of 1.0 millimeters to 8.0 millimeters, preferably to 2.0 mm. To 6.0 mm., in combination with a resilient, pliable rubber or polymer material having a thickness in the range of only 1.0 to 8.0 mm, preferably 2.0 mm to 6.0 mm, produces a laminate having good “chew resistance” and having the additional feature of being quite safe because the thin, resilient polymer material is readily deformed and is not hard and because the thick felt tends to dissipate the forces produced when a dog or other animal bites the toy. Accordingly, the ratio of the thickness of the felt covers 80, 81 to the thickness of polymer material comprising halves 60 and 61 is in the range of 1:6 to 1:0.15, preferably 1:3 to 1:0.5.

FIGS. 10 to 12 illustrate another embodiment of the toy of the invention generally indicated by reference character 200 and including a hollow cylindrical core 211 fabricated from pliable elastic rubber, from another elastomer, or from any other desired material. Pieces 212, 213 of felt or another desired material can, if desired, be adhesively secured or otherwise affixed to the outer cylindrical surface 228 of core 211. Fabric pieces 212, 213 are shaped and dimensioned and applied to surface 228 such that a space or groove of substantially constant width between the pieces 212, 213 is formed. This groove is filled with an elastic rubber material to form strip 214. Alternately, one or more fabric pieces can be utilized to completely cover surface 228, after which a strip 214 of material can be attached on or in the fabric to form a strip 214 dividing the fabric into sections on either side of the strip 214. Strip 214 presently has a width in the range of one-sixteenth to seven-sixteenths of an inch, preferably two-sixteenths to five-sixteenths of an inch. The width of strip 214 can vary as desired.

Cylindrical end piece 218 includes member 219 made from rubber or another elastomer or other desired material and includes a fabric piece 220 adhesively secured or otherwise secured to piece 219. Piece 218 includes inner circular surface 206. Cylindrical aperture 217 is formed through piece 218. Piece 218 is secured to the end 205 of core 11 and/or to the end 222 of fabric pieces 212, 213. Instead of utilizing piece 218, each half 300 of core 211 can include a semi-circular end 238 comparable to end 237 FIG. 12), except that a semi-circular opening 239 is be formed through end 238 so that when the upper and lower halves of core 211 are glued together to form core 211, an opening comparable to opening 217 is formed through ends 238.

Rope 230 includes distal end 234, proximate end 235, and an intermediate portion 236 extending between the distal and proximate ends 234, 235. An anchor 231 is formed at distal end 234. The anchor 231 can be formed by tying end 234 into the knot 231 shown, by tying end 234 around a rod, by affixing a glass ball to end 234, etc. Any method or apparatus can be utilized to form an anchor at distal end 234 as long as the anchor is shaped and dimensioned such that it can not fit or be pulled through aperture 217.

FIG. 11 illustrates toy 200 fully assembled.

FIG. 12 illustrates the lower semi-cylindrical half 300 of core 211, which includes edge surface 204 and edge surface 233. The upper half of core 211 presently has a shape and dimension equivalent to the lower half of core 211. When the two semi-cylindrical halves of core 211 are glued together along their edge surfaces 204, the hollow cylindrical core 211 illustrated in FIG. 10 results. When the two semi-cylindrical halves of core 11 are glued together along edges 233, circular diaphragm 232 (FIG. 10) results.

Diaphragm 232 divides the inner area of toy 200 into two compartments 229 and 229A. Compartment 229A is fully sealed and enclosed by diaphragm 232 and a portion of core 211. Compartment 229 is not sealed because of aperture 217, however, compartment 229 is circumscribed and enclosed by another portion of core 211.

Toy 200 can be manufactured in any desired manner, however, it is presently preferred that knot 231 (or some other anchor) be positioned in compartment 229 when the upper and lower halves of core 211 are glued together along edges 204, 233 (or are otherwise affixed to one another) to form hollow cylindrical core 211. After core 211 is formed to produce sealed compartments 229 and 229A, compartment 229A is filled with air or some other desired gas or liquid and compartment 229 is filled with air and anchor 231. The intermediate portion 236 of rope 230 extends from anchor 231, out through aperture 217, and to proximate end 235. Felt or fabric layers 212, 213 are then applied and secured to outer surface 228 in the manner earlier described. Or, if desired, a felt layer 212, 213 need not be applied to core 211.

When layers 212, 213 are applied to core 211, the portion of rope 230 extending outwardly from aperture 217 is usually temporarily folded into a compact configuration and secured in that configuration with a rubber band, string, etc. The folding of a portion of rope 230 into a compact configuration facilitates the application of felt layers 212, 213 and facilitates transport of core 211 through the remainder of the manufacturing process.

In use of the toy 200 depicted in FIG. 11, the portion of rope 230 extending outwardly from aperture 217 is manually grasped and used to throw the toy away from the user so a dog or other animal can retrieve the toy 200 and bring toy 200 back to the user. Toy 200 can also be utilized as a toy for young or adult human beings. Toy 200 need not be thrown but can be given to a dog to play with, can be used by letting a dog grasp the felt covered body of the toy in its mouth to pull on the body while the train pulls on rope 230, etc.

A manufacturing process for toy 200 is set forth in FIG. 13 and includes the step 250 of molding the top half and bottom half of the toy with a diaphragm formed intermediate the ends of each half so that the diaphragm 232 divides the inner hollow area into two compartments, one compartment 229A to be sealed when the top and bottom 300 semi-cylindrical halves are joined, and the other compartment 229 not to be sealed when the bottom halves are joined.

In step 251, an anchor is formed at the distal end 234 of rope 230. This is followed by step 252 in which the proximate end 235 is extended through opening 217 (or 239) so that anchor 231 is positioned in the unsealed compartment 229 of toy 200. In step 253, glue is applied along the seam edges 204, 233 of each half, the halves are pressed together along the seam edges to form core 211 having a seam line defined by edges 204 and, to form sealed compartment 229A and unsealed compartment 229 containing anchor 231. The member is then, in step 254, placed in a mold to heat and cure the adhesive that extends along seam edges 204, 233. Felt, another fabric, or another material can then, if desired be applied to outer surface 228 of core 211.

In FIG. 10, one end of rope 230 is in compartment 229. If desired, a pair of apertures 242, 243 can be formed through piece 218 and/or in the cylindrical wall circumscribing compartment 229. The apertures are sized are positioned to permit an end of rope 230 to be threaded through aperture 243 into compartment 229, through compartment 229, and through aperture 242 to a location outside of compartment 229 and surface 228. In this fashion, rope 230 extends completely through compartment 229 and both ends of rope 230 are located outside compartment 229. Knots or other anchor means can be formed in the ends of the rope such that the ends of the rope can not be pulled through apertures 242, 243 into compartment 229. As used herein, the term rope refers to a length of pliable material. The pliable material can be woven, extruded (like pliable plastic line), or otherwise formed. Conventional woven cotton or nylon rope is, however, presently preferred in the practice of the invention. Rope 230 can have a conventional cylindrical shape like that shown in the drawings, can be substantially flat (if a leather strap is used), or can take on any desired shape and dimension.

Compartment 229 is, as noted, presently preferably filled with air. Sand, rubber, foam, or any other desired material can completely or partially fill compartment 229. Compartment 229 is presently preferably not sealed. If desired, compartment 229 can be sealed and filled with any desired solid, liquid, gas or combination thereof. Compartment 229 can be filled with any desired solid, liquid, gas or combination thereof.

As used herein, the term fabric includes material made by weaving, felting, knitting, knotting, bonding, or crocheting natural or synthetic fibers and/or filaments. Examples of natural fibers are, without limitation, cotton, wool, and silver. Examples of synthetic fibers are, without limitation, nylon, rayon and Kevlar™. Felts are, are earlier noted, presently preferred in the practice of the invention.

Another embodiment of the invention is illustrated FIG. 14 and is generally indicated by reference character 301. Cylindrical toy 301 comprises a compressibly elastically deformable hollow thin walled elastomer core 310 (FIG. 25) that circumscribes and encloses a selected compressible gaseous volume 330. Gaseous volume 330 typically comprises air. Toy 301 includes center 321 that is equidistant from the circular top (not visible) and circular bottom 311 of toy 301. The circular top is equivalent in size to bottom 311 and is parallel to and spaced apart from bottom 311. Cylindrical outer wall 312 extends between and interconnects the circular top and bottom 311. Points on the outer and inner surfaces of wall 312 are at varying distances from center 321. Wall 312, the circular top, and circular bottom 311 can have any desired thickness but preferably each are less than about eight millimeters thick.

A fabric cover is affixed to the outer surface of core 310 and has a selected thickness. The ratio of the thickness of the fabric cover to the thickness of the wall 312 is in the range of 1:6 to 1:0.15. The ratio of the thickness of the fabric cover to the thickness of the circular top or circular bottom 311 is in the range of 1:6 to 1:0.15. At least one elongate strip of material can, if desired, extend over the outer surface of the core as a line of demarcation to separate the fabric cover into at least two areas, one on either side of the strip of material. This line of demarcation is not shown in FIG. 14 but could, by way of example and not limitation, be comparable to the line of demarcation 14 illustrated in FIG. 1.

At least one aperture 308 (FIGS. 24 and 25) is formed in core 310. An aperture 305 can also, if desired, be formed through the fabric cover. The fabric cover includes a circular portion 303 covering the circular top of core 310, includes a circular portion 304 covering the bottom 311 of the core 310, and includes a cylindrical portion or wall 302 covering the cylindrical wall 312 of core 310. Wall 302 extends between and interconnects portions 303 and 304. A hollow sound device 307 is inserted in aperture 308. Device 307 produces a sound audible to an animal. As used herein, a sound audible to an animal is defined as a sound in the range of frequencies that is audible to a dog because a sound in this range of frequencies can in most cases be heard by human beings and many other animals. The sound device 307 illustrated in FIG. 16 is presently preferred in the practice of the invention, but the sound device 330 illustrated in FIG. 15 can be utilized, as can be any other desired sound device.

Sound device 307 includes hollow cylindrical leg 338 and upstanding lip or rim 337 that is connected to and extends outwardly from leg 338. Apertures 331 and 332 are formed in the top of and extend downwardly into leg 338. As is illustrated in FIG. 17, a semi-circular, hollow, tapered toe 341 is provided with a reed or a thin piece of plastic 342 that extends downwardly over and slightly spaced apart from the opening in toe 341. When air travels upwardly into toe 341 in the direction of arrow 335, the air also passes by reed 342 and causes reed 342 to vibrate. Reed 342 or the movement of reed 342 in conjunction with the proximity of toe 341 produces sound, typically a sound with a high pitch. The construction of a wide variety of sound devices is well known in the art, as are a variety of sounds that such devices can produce and that have a high, low, or intermediate pitch. Any desired sound device can be utilized in the practice of the invention. Device 307 produces sound only when air flows through device 307 at a selected rate of flow. If the rate of flow of air through device 307 is too slow, device 307 will not produce sound. It is desirable in the practice of the invention that device 307 produce sound when the top and bottom 311 of toy 301 are compressed rapidly by a dog holding toy 301 in its mouth. The rate of flow of air through device 307 required to cause device 307 to produce sound can be varied as desired. Air flowing upwardly in the direction of arrow 335 in FIG. 17 flows past reed 342, into toe 341 in the manner indicated by arrow 340, and out through the apertures 331, 332 formed in the top of device 307. Air flowing out through apertures 331, 332 travels in the directions indicated by arrows 333 and 334.

The hollow sound device 330 illustrated in FIG. 15 operates in the same manner as device 307. Air passing upwardly into device 330 travels over a reed (not shown) and into a toe (not shown) and out through aperture 352 in the direction of arrow 351. Device 330 includes conical leg 353 having a top including circular edge 354. Conical leg 353 is sized such that it can be forced downwardly through an aperture 308 to distend the elastic material around aperture 308 to permit leg 353 to be pushed through aperture 308 and into the interior of a toy 301. The diameter of edge 354 is, however, significantly greater than the diameter of opening 308 such that once leg 353 is forced through aperture 308 into the interior of toy 301, leg 353 can not be readily pulled back out through aperture 308.

One method for making a toy 301 is illustrated in FIGS. 18 to 21. In FIG. 18 a compressibly elastically deformable hollow thin-walled elastomer core 410 is provided. The core 410 circumscribes a compressible gaseous volume 430, which volume typically is air. The core includes a center 421. Center 421 is equidistant from the circular top (not visible) and circular bottom 411 of core 410. The circular top is equivalent in size to bottom 411 and is parallel to and spaced apart from bottom 411. Cylindrical outer wall 412 extends between and interconnects the circular top and circular bottom 411. Points on the outer and inner surfaces of wall 412 are at varying distances from center 421. Wall 412, the circular top, and the circular bottom 411 can have any desired thickness but preferably are less than about eight millimeters thick. At least one aperture 408 is formed in core 410.

As is illustrated in FIG. 19, a removable plug 406 is fixedly inserted in aperture 408. Insertion of the plug is important in the practice of the method of the invention because when a fabric cover is affixed to the outer surface of core 410, pressure and heat are used. If the plug 406 is not utilized and is not permitted to function to maintain air inside core 410 when the pressure is applied, the core 410 can collapse, ruining the attempt to apply the fabric cover.

After the plug 406 is inserted, a fabric cover is affixed to the outer surface of core 410 using pressure and a material that causes the fabric cover to adhere to the core 410. The fabric cover has a selected thickness. The ratio of the thickness of the fabric cover to the thickness of the wall 412 is in the range of 1:6 to 1:0.15. The ratio of the thickness of the fabric cover to the thickness of the circular top or circular bottom 311 is in the range of 1:6 to 1:0.15. At least one elongate strip of material can, if desired, also be applied to and extend over the outer surface of the core as a line of demarcation to separate the fabric cover into at least two areas, one on either side of the strip of material. This line of demarcation is not shown in FIG. 14 but could, by way of example and not limitation, be comparable to the line of demarcation 14 illustrated in FIG. 1. Methods for applying the fabric cover and lines of demarcation are described earlier herein. Any desired method can be utilized to apply the fabric cover and lines of demarcation. The material comprising the fabric cover can vary as desired, but presently preferred materials are also described earlier herein. An aperture 405 can also, if desired, be formed through the fabric cover. The fabric cover includes an upper circular portion (not shown) covering the outer surface of the circular top of core 410, includes a lower circular portion (not shown) covering the outer surface of the bottom 411 of the core 410, and includes a cylindrical portion or wall 402 extending around and covering the cylindrical wall 412 of core 410. Wall 402 interconnects the upper and lower circular portions of the fabric cover.

After the fabric cover is applied, plug 406 is removed and sound device 307 is inserted in aperture 408 in the manner shown in FIG. 21. Rib 337 of device 307 compresses and indents a portion of the cylindrical side of aperture 408 and functions to anchor device 307 in aperture 408. A shown in FIG. 14, it is preferred that a cylindrical piece of fabric material or “plug” 306 is used to cover the top of sound device 307 such that animal toy 307 appears to be completely covered by fabric material. Piece 306 can also comprise a flap that is partially attached to and folded back onto the fabric cover such that piece 306 can be fold off the fabric cover onto the top of device 307. Piece 306 or some other way of concealing the top of device 307 is important because a dog can attempt to remove the sound device 307 from core 410. If the location of the sound device 307 is covered or disguised, it makes it more difficult for a dog to find and remove or damage device 307.

It is preferred that core 410 include an area 413 that is thicker than the top, bottom 411, or wall 412 of core 410. The increased volume or size of area 413 functions to protect sound device 307 and make it more difficult for an animal to remove device 307 from core 410.

Another method for making a toy 301 is illustrated in FIGS. 22 to 25. In FIG. 22 a compressibly elastically deformable hollow thin-walled elastomer core 310 is provided. The core 310 completely sealingly circumscribes a compressible gaseous volume 330, which volume typically is air. The core includes a center 321. Center 321 is equidistant from and generally centered with respect to the circular top (not visible) and circular bottom 311 of core 310. The circular top is equivalent in size to bottom 311 and is parallel to and spaced apart from bottom 311. Cylindrical outer wall 312 extends between and interconnects the circular top and circular bottom 311. Points on the outer and inner surfaces of wall 312 are at varying distances from center 321. Wall 312, the circular top, and circular bottom 311 (or wall 412, wall 512, bottom 411, bottom 511, etc.) can have any desired thickness including any of the wall thicknesses previously discussed herein for other embodiments of the invention, but presently preferably are less than about eight millimeters thick. Core 310 includes a portion 313 that is formed in wall 312 and that has greater thickness and mass than the remainder of wall 312. Portion 313 functions, as will be seen, to provide support for a sound device 307 that is subsequently inserted in core 310. Another important function of portion 313 is to made core asymmetric. Such asymmetry promotes the erratic bouncing of toy 301 because a portion of the weight of the toy is not equally distributed about the wall 312. Since toy 301 can take on any desired shape and dimension, the asymmetry caused by portion 313 is important because it causes erratic bouncing of toy 301 even when toy 301 is spherical. If desired, portion 313 can be omitted, i.e., wall 312 can have a constant thickness throughout. Omitting portion 313 reduces the likelihood that toy 301 will bounce erratically, particularly if toy 301 is spherical. In addition, even if portion 313 is not utilized and wall 312 has the same thickness at all points, simply forming hole 308 in wall 312 and inserting device 307 tends to make toy 301 asymmetric because the device 307 ordinarily does not have the same mass as the material in wall 312. An aperture 308 can, if desired, be formed in the top or bottom 311 of core 310 or at any desired location in core 310. Since, as noted, one function of portion 313 is to promote asymmetry due to the increased weight or mass that portion 313 adds to a portion of core 310. As would be appreciated by those of skill in the art, portion 313 can be located at any desired location on or in core 310. The shape and dimension of portion 313 can vary as desired. Two or more portions 313, each having the same or different shape and dimension, can be formed on or in core 310. A portion 313 can, if desired, not be attached to the wall of core 310 in the manner of portion 313, but can be inside core 310 and be free to move around therein. The thickness of the wall of core 310 can be varied as desired to promote either an erratic bounce or a uniform bounce of a toy 301 along a straight line.

A fabric cover is affixed to the outer surface of core 310 using pressure and a material that causes the fabric cover to adhere to the core 310. Core 310 can, because core 310 completely sealingly circumscribes the gaseous volume 330, withstand the pressure that ordinarily must be applied in order to affix the fabric cover to the core 310. Consequently, core 310 does not collapse when the pressure is applied. FIG. 23 illustrates the fabric cover applied to core 310. The fabric cover has a selected thickness. The ratio of the thickness of the fabric cover to the thickness of the wall 312 is in the range of 1:6 to 1:0.15. The ratio of the thickness of the fabric cover to the thickness of the circular top or circular bottom 311 is in the range of 1:6 to 1:0.15. At least one elongate strip of material can, if desired, also be applied to and extend over the outer surface of the core as a line of demarcation to separate the fabric cover into at least two areas, one on either side of the strip of material. This line of demarcation is not shown in FIG. 14 but could, by way of example and not limitation, be comparable to the line of demarcation 14 illustrated in FIG. 1. Methods for applying the fabric cover and lines of demarcation are described earlier herein. Any desired method can be utilized to apply the fabric cover and lines of demarcation. The material comprising the fabric cover can vary as desired, but presently preferred materials are also described earlier herein. The fabric cover includes an upper circular portion 303 (FIG. 14) covering the outer surface of the circular top of core 310, includes a lower circular portion 304 (FIG. 14) covering the outer surface of the circular bottom 311 of the core 310, and includes a cylindrical portion or wall 302 extending around and covering the cylindrical wall 312 of core 310. Wall 302 interconnects the upper 303 and lower 304 circular portions of the fabric cover.

After the fabric cover is applied, an aperture 308 is drilled or otherwise formed in core 310. Aperture 308 includes a countersunk portion that receives the top or head 400 of device 307 so that the top 400 of device 307 is flush with or inset with respect to the outer surface of core 310. An aperture 305 is also formed through the fabric cover. The aperture 308 can be formed at this point in the process because fabric cover 302 has been applied, and the air inside core 310 is no longer required to function to prevent the collapse of core 310 when pressure is applied to the outside of core 310. FIG. 24 illustrates core 310 and the fabric cover after apertures 308 and 305 are formed.

Sound device 307 is inserted in aperture 308 in the manner shown in FIG. 25. Rib 337 of device 307 compresses and indents a portion of the cylindrical side of aperture 308 and functions to anchor device 307 in aperture 308. Any desired method or apparatus can be utilized to fix device 307 in aperture 308 or in core 310. As shown in FIG. 14, it is preferred that a cylindrical piece of fabric material or “plug” is used to cover the top of sound device 307 such that animal toy 301 appears to be completely covered by fabric material. This is important because a dog or other animal can attempt to remove the sound device 307 from core 310. If the location of the sound device 307 is covered or disguised, it makes it more difficult to a dog to find and remove or damage device 307.

In use of the toy 301 (or 401 or 501), the toy is given to a dog or other animal, or is thrown so that the dog has to retrieve the toy. When the dog compresses the toy 301 in its mouth, it compresses air in compressible volume 330, forcing air outwardly through device 307 in the manner indicated by arrows 335, 340, 333, and 334 in FIGS. 16 and 17. This causes device 307 to produce a sound that the dog hears. When the dog releases the compressive pressure on toy 301, the toy elastically returns to the normal configuration illustrated in FIG. 14. When the toy elastically returns to the normal configuration illustrated in FIG. 14, air is drawn through device 307 back into volume 330 in directions opposite the directions indicated by arrows 333, 334, 340, and 335. When air is drawn back into volume 330, device 307 also produces sound that the dog can hear. If desired, however, device 307 need only produce sound when air travels through device 307 in one direction-either when air is expelled from volume 330 through device 307 or when is air drawn through device 307 into volume 330. One particular advantage of toy 301 is that device 307 makes the toy safer to use. When it is dusk or dark and it is difficult for an animal to see the toy, sound made by the toy helps the animal locate the toy. Similarly, when the animal is in high grass and has difficulty seeing toy 301, any sound made by the toy 301 helps the animal locate the toy. Since toy 301 is compressible, the toy will typically, although not necessarily, generate noise when the toy strikes the ground or an object and is compressed. When the toy is compressed, air is forced outwardly through device 307, producing sound audible to the animal.

Still another method for making a toy 301 is illustrated in FIGS. 26 to 28. In FIG. 26 a compressibly elastically deformable hollow thin-walled elastomer core 510 is provided with a fabric cover affixed to the outer surface of core 510. The core 510 completely sealingly circumscribes a compressible gaseous volume 530, which volume typically is air, but which can consist of any other gas or gasses or fluid or fluids. The core includes a center 521. Center 521 is equidistant from the circular top (not visible) and circular bottom 511 of core 510. The circular top is equivalent in size to bottom 511 and is parallel to and spaced apart from bottom 511. Cylindrical wall 512 extends between and interconnects the circular top and circular bottom 511. Points on the outer and inner surfaces of wall 512 are at varying distances from center 521. Wall 512, the circular top, and the circular bottom 511 can have any desired thickness, but preferably are less than about eight millimeters thick. Toy 501 can take on any desired shape and dimension.

The ratio of the thickness of the fabric cover to the thickness of the wall 512 is in the range of 1:6 to 1:0.15. The ratio of the thickness of the fabric cover to the thickness of the circular top or circular bottom 511 is in the range of 1:6 to 1:0.15. At least one elongate strip of material can, if desired, also be applied to and extend over the outer surface of the core as a line of demarcation to separate the fabric cover into at least two areas, one on either side of the strip of material. This line of demarcation is not shown in FIG. 14 but could, by way of example and not limitation, be comparable to the line of demarcation 14 illustrated in FIG. 1. The material comprising the fabric cover can vary as desired, but presently preferred materials are also described earlier herein. The fabric cover includes an upper circular portion (not shown) covering the outer surface of the circular top of core 510, includes a lower circular portion (not shown) covering the outer surface of the bottom 511 of the core 510, and includes a cylindrical portion or wall 502 extending around and covering the cylindrical wall 512 of core 510. Wall 502 interconnects the upper and lower circular portions of the fabric cover.

An aperture 508 is drilled or otherwise formed in core 510. An aperture 505 is also formed through the fabric cover. Apertures 505 and 508 are illustrated in FIG. 27. The aperture 508 can be formed at this point in the process because fabric wall 502 has been applied, and the air inside core 510 is no longer required to function to prevent the collapse of core 510 when pressure is applied to the outside of core 510.

Sound device 307 is inserted in aperture 508 in the manner shown in FIG. 28. Rib 337 of device 307 compresses and indents a portion of the cylindrical side of aperture 508 and functions to anchor device 307 in aperture 508. Any desired method or apparatus can be utilized to fix device 307 in aperture 508 or in core 510. As shown in FIG. 14, it is preferred that a cylindrical piece of fabric material or “plug” is used to cover the top of sound device 307 such that animal toy 501 appears to be completely covered by fabric material. This is important because a dog or other animal can attempt to remove the sound device 307 from core 510. If the location of the sound device 307 is covered or disguised, it makes it more difficult to a dog to find and remove or damage device 307.

Still another embodiment of the toy includes a rib that is formed inside of core 510 and that is indicated in FIG. 27 by dashed lines 520. Sound device 307 is mounted in rib 520 such that compressing toy 501 causing air to move through device 307 from one side of rib 520 to the other side of rib 520 such that device 307 produces a sound that can be heard by a dog or other animal. While it is possible that this embodiment of the invention will function to produce sound even if an aperture 508 is not formed through core 510, it is preferred that an aperture 508 be formed in core 510 to facilitate the ready travel of air through device 307. Installing device 307 in rib 520 makes it much more difficult for a dog to damage device 307. The dog would have to tear open core 510 to access device 307. Rib 520 and device 307 preferably completely divide the inner volume 530 into two separate compartments.

In still another embodiment of the invention, the process set forth in FIGS. 18 to 21 is utilized, except that in FIG. 19 device 307 is installed instead of plug 406, and a plug is installed directly in device 307 to prevent air from escaping from volume 430 while the fabric cover is applied. After the fabric cover is applied, the plug blocking device 307 is removed to permit air to flow through device 307 when the toy 401 is compressed.

The soft fabric cover described herein on the toys of the invention is, as noted, important because it reduces the risk of injury to an animal. The processes set forth in FIGS. 18 to 25 are central to the invention because they enable application of the fabric cover to be achieved under pressure and still allow a sound device to be installed and concealed in a toy.

Another embodiment of the invention comprises molding or otherwise forming an opening 331 (FIG. 22) in the core 310 when core 310, or a portion of core 310, is being produced. The opening 331 is shaped and dimensioned such that when air travels through the opening 331 (either traveling from the inside of core 310 out through opening 331 or vice-versa) at a selected flow rate audible sound is produced that can be heard by a dog or other animal. The advantage of forming opening 331 during the molding of core 310 is that the resulting animal toy 301 does not require the drilling or other formation of an aperture 308 in core 310 and does not require the subsequent insertion of a separate sound device 307 in aperture 308. Sound device 307 and aperture 308 are not required because the opening 331 functions to produce sound when air passes therethrough. In a similar manner, the aperture 508 formed in core 510 in FIG. 27 can be shaped and dimensioned to produce sound when air travels into or out of core 510 at a desired flow rate. When aperture 508 is so formed, it is not necessary to insert device 307 in aperture 508 to produce sound. Aperture 331 and aperture 508 (when aperture 508 is formed to produce sound when air passes therethrough) demonstrate embodiments of the invention in which separate sound devices 307 need not be inserted in a toy 301, 501.

One or more bulkheads can be formed inside a core 310, 410, 510 of a toy 301, 401, 501. The bulkheads can extend partially or completely across the volume inside the core. A bulkhead can include an aperture formed therein to produce noise when air passes therethrough, and can include a sound device 307 inserted in the bulkhead to produce noise when air passes through the sound device 307.

The outer surface of a sound device 307 can—in addition to or in place of a rib 337 that alters the shape of an opening 308, 408, 508—be made of a material that frictionally engages the material comprising the wall of the opening 308, 408, 508 that contacts the outer surface of device 307. This makes it more difficult for an animal to remove device 307 from an opening 308, 408, 508. In this respect, soft polymers tend to adhere frictionally to one another more effectively that hard smooth polymers. Or, a soft polymer with a high coefficient of friction can function to adhere to the surface of a hard smooth polymer or other material.

Another method for making a toy of the general type illustrated in FIGS. 18 to 28 is illustrated in FIG. 29. In step 340, a compressibly elastically deformable spherical hollow thin-walled rubber (or other elastomer) core is provided. The core includes an aperture shaped and dimensioned to receive a squeaker. The aperture can be formed in any desired manner, including by drilling or by being formed when the core (or a part of the core) is formed in a mold. The shape and dimension of the core can vary as desired and need not be spherical. While not necessary, the aperture preferably includes an inset or countersunk portion similar to the inset portion 509 illustrated in FIG. 27. The cap or top 400 of the squeaker 307 seats in such inset portion so that the top 400 of the squeaker 307 is flush with the outer surface of the core.

In step 341, adhesive is applied to the exterior of the rubber core, after which a layer of felt is applied in step 342. The core-adhesive-felt combination is heated in step 343, after which an opening is formed in the felt in step 344. The opening is in registration with the aperture formed in the core. The opening is made by cutting through the felt and removing felt from about the aperture. A squeaker 307 is inserted in the opening in the core in step 345. In step 346, a piece of felt is glued over the top 400 of the squeaker 307 to disguise the location of the squeaker. A iron or other instrument is used in step 347 to flatten and smooth the piece of felt.

The ability to produce an animal toy according to the method set forth in FIG. 29 was a surprising result because it had been suggested that attempting to apply felt to a rubber core when there was an aperture in the core would cause the core to collapse. When the core has a wall thickness in the range set forth earlier herein, the core appears to retain its shape and not to collapse when felt is applied and the core and felt (and adhesive) are compressed and heated in a mold. If undue compressive pressure is applied to the core-adhesive-felt, the core likely will collapse. Only minimal experimentation is normally required to determine a reasonable compressive pressure that will not cause the core-adhesive-felt to collapse when heated to about 135 degrees C. to 145 degrees C. for five minutes. It may be possible to apply no or only minimal compressive force to the felt and core when the mold contacts the felt because heat alone will cure or otherwise affect the adhesive such that the felt or other fabric properly adheres to the core. While the elevated temperature utilized to heat the mold—and therefore the felt and adhesive—is presently 135 degrees C. to 145 C, any desired elevated temperature in excess of the ambient room temperature of about 76 degrees F., preferably in excess of 100 degrees F., most preferably in excess of 200 degrees F. can be utilized to heat the felt and adhesive. The length of time for which the felt and adhesive and core are heated can vary as desired, but presently typically is in the range of one minute to thirty minutes, preferably one minute to twenty minutes, and most preferably one minute to ten minutes.

A further method for producing an animal toy of the general type illustrated in FIGS. 18 to 28 is illustrated in FIG. 30. In step 350, a compressibly elastically deformable spherical hollow thin-walled rubber (or other elastomer) core is provided. The core includes an aperture shaped and dimensioned to receive a squeaker. The aperture can be formed in any desired manner, including by drilling or by being formed when the core (or a part of the core) is formed in a mold. The shape and dimension of the core can vary as desired and need not be spherical. While not necessary, the aperture preferably includes an inset or countersunk portion similar to the inset portion 509 illustrated in FIG. 27. The cap or top 400 of the squeaker seats in such inset portion so that the top 400 of the squeaker 307 is flush with the outer surface of the core and does not extend upwardly past the outer surface of the core.

In step 351, a temperature resistant squeaker is inserted in the aperture formed in the core. The squeaker is formed of a material, preferably a polymer, that will not melt or deform at the elevated temperature at which the core-adhesive-felt typically are heated to cure or otherwise affect the rubber adhesive or other adhesive used to secure the felt or other fabric to the core. Using such a temperature resistant squeaker significantly simplifies the process of producing an animal toy that includes a squeaker. As used herein with respect to the material(s) comprising a squeaker, a squeaker is temperature resistant if it functions normally after being subjected to the elevated temperature applied to the felt and adhesive to cure or otherwise affect the adhesive to secure the felt to the core. The squeaker will function normally after being subjected to an elevated temperature greater than 100 degrees F., preferably after being subjected to an elevated temperature greater than 200 degrees F., and most preferably after being subjected to an elevated temperature greater than 300 degrees F. While the shape and dimension of the temperature resistant squeaker can vary as desired, it is presently preferred that the squeaker include a reed 342 that vibrates when air passes over the reed and that is fabricated from a temperature resistant material. A temperature resistant reed squeaker apparently has not been utilized to facilitate the manufacture of a fabric covered squeaker toy for animals.

After the temperature resistant squeaker is inserted in the core, rubber adhesive or another desired adhesive or fastening material is applied to the outer surface of the rubber core in step 352. A layer of felt is applied to the layer of adhesive in step 353. In step 354, the core-adhesive-felt is compressed and heated, typically to about 300 degrees F., to cure the rubber adhesive and to compact and smooth the layer of felt to make it more difficult for an animal to tear the felt off the rubber core.

The ability to produce an animal toy according to the method set forth in FIG. 30 was a surprising result because it had been suggested that attempting to heat a squeaker would not work because the heat would melt or deform the squeaker. It was discovered that it was feasible to produce a squeaker from a polymer that would not melt at the elevated temperature used to compress and cure the adhesive that secured the felt to the core and to compress and cure the adhesive that was used to form seams between pieces of felt that were attached to the core. Using such a temperature resistant squeaker significantly reduces the time required to produce a felt covered squeaker animal toy. A particular advantage of using the temperature resistant squeaker is that the felt layer on the completed toy is substantially continuous, which makes it more difficult for an animal to locate the squeaker and remove the squeaker from the toy. When a piece of felt is removed to insert the squeaker and is then glued back in place over the squeaker, it is easier for an animal to locate the squeaker. Another feature that makes it more difficult for an animal to locate and remove the squeaker is countersinking the head of the squeaker in the manner earlier described herein. A further feature that makes it more difficult for an animal to remove the squeaker is using a squeaker 330 that has a tapered base 353. The base 353 has a diameter greater than that of the aperture formed in the core of the toy, and has a lip 354, both of which make removal of the squeaker from the core difficult. Still another feature that makes it more difficult for an animal to remove the squeaker is to utilize in the core a reinforced, stronger area 413 (FIG. 18) around the squeaker that is thicker than other areas of the wall of the core.

Another method for making a toy of the general type illustrated in FIGS. 18 to 28 is illustrated in FIG. 31. In step 358, a compressibly elastically deformable spherical hollow thin-walled rubber (or other elastomer) core is provided. The core includes an aperture shaped and dimensioned to function as a squeaker and to produce noise when air moves through the aperture. Forming the aperture in this manner obviates having to later insert a squeaker in the core. The aperture can be formed in any desired manner, including by drilling or by being formed when the core (or a part of the core) is formed in a mold. The shape and dimension of the core can vary as desired and need not be spherical.

In step 359, adhesive is applied to the exterior of the rubber core, after which a layer of felt is applied in step 359. If the felt has an adhesive backing, then step 359 can be skipped and adhesive need not be applied to the outer surface of the rubber core. The core-adhesive-felt combination is compressed, heated, and cured in step 361.

Another method for making a toy of the general type illustrated in FIGS. 18 to 28 is illustrated in FIG. 32. In step 364, a compressibly elastically deformable spherical hollow thin-walled rubber (or other elastomer) core is provided. The core includes an aperture 408 shaped and dimensioned to receive a squeaker. The aperture does not, however, extend completely through the wall of the core. Instead, a thin membrane-indicated by dashed lines 408A in FIG. 18—extends across a portion of aperture 408. Membrane 408A ensures that the interior of the core is sealingly enclosed. As described below, when a squeaker 307 is inserted in the aperture 408, the membrane 408A is punctured. The membrane can be fabricated from any material including a polymer, paper, etc.

The aperture 408 can be formed in any desired manner, including by drilling or by being formed when the core (or a part of the core) is formed in a mold. Since the formation of a membrane 408A is required, molding is believed to be a more likely alternative for forming aperture 408. The shape and dimension of the core can vary as desired and need not be spherical. While not necessary, the aperture preferably includes an inset or countersunk portion similar to the inset portion 409 illustrated in FIG. 18. The cap or top 400 of the squeaker 307 seats in such inset portion so that the top 400 of the squeaker 307 is flush with the outer surface of the core.

In step 365, adhesive is applied to the exterior of the rubber core, after which a layer of felt is applied in step 366. The core-adhesive-felt combination is heated in step 367, after which an opening is formed in the felt in step 368. The opening is in registration with the aperture formed in the core. The opening is made by cutting through the felt and removing felt from about the aperture. A squeaker 307 is inserted in the opening in the core in step 369. The squeaker 307 punctures membrane 408A and extends into the interior of the rubber core. In step 370, a piece of felt is glued over the top 400 of the squeaker 307 to disguise the location of the squeaker. An iron or other instrument is used in step 371 to flatten and smooth the piece of felt.

The squeaker animal toys depicted in FIGS. 14, 21, 25, and 28 can, if desired, include one or more other openings formed through the wall of the core to receive other squeakers, to receive the end of a rope, and to receive any other object incorporated in the toy.

The squeaker animal toy cores depicted in FIGS. 14, 21, 25, and 28 are substantially hollow. The hollow gas filled interior of each of the cores comprises a large part of the overall volume or space occupied by the core. If desired, the interior of the core of each of the toys—or all or part of the material comprising each core—can consist of foam, of a honeycomb-shaped lattice, of solid rubber or of any other desired material or structure. For example, the spherical (or other shaped) core can be filled with foam or some other material, or, can consist completely of urethane foam, of solid rubber, or of some other material. If desired, a hollow can be formed in or through the solid core to receive a squeaker. Adhesive and a fabric cover are attached to the solid core in the manner earlier described. If desired, felt or another fabric can be attached to a core with an adhesive or other fastening system that does not require heating the fabric or core or adhesive. The core can be pliable or elastic. If a polymer film is used to fabricate all or a part of the core, the foam can be rigid and hard, soft and pliable, elastic, etc. as desired.

Any conventional squeaker can be utilized in a core. One conventional hollow squeaker is self-contained and comprises a bottle-shaped elastic pliable polymer member with a squeaker mounted in the “neck” or “top” of the bottle. The neck is attached to and is in gaseous communication with the hollow body or bladder of the squeaker. When the hollow body of the polymer member is squeezed and compressed from its original shape, air inside the body of the polymer member is forced out through the squeaker to produce sound. When the body is released (after being squeezed), the body elastically returns to its original hollow shape and draws air through the squeaker and back into the body. This kind of conventional squeaker is sometimes used in plush toys.

FIGS. 33 to 36 illustrate a sound module 372 that can be utilized on any animal toy, including a plush toy and the toys described herein, by mounting or placing the sound module anywhere on the toy including, but not limited to, inside the toy, on the exterior of the toy, and partially embedded in the toy.

Module 372 includes a sound generator (not shown). The sound generator includes a motion sensor and a system for randomly selecting one or more sounds and then, when there are two or more sounds selected, combining the sounds and producing the sounds over a speaker in the sound generator. Sound generators that are triggered by motion of the sound generator, by another sound, by an on-off switch, etc. are known and the construction of such is not detailed here. However, a sound generator that is specifically produced for animals toys and that randomly produces and combines sounds to produce a variety of different sounds as described herein apparently is not known.

In FIG. 33, module 372 has been activated by movement of the toy (not shown) on which module 372 is mounted. Movement of the toy also moved module 372, a motion sensor in module 372 detected the movement, and the motion sensor therefore activated module 372. When module 372 is activated, a software program or other random selection system in module 372 randomly selects the two note sequence 373 consisting of the B below middle C and middle C (the note produced when the middle C key on a piano is struck), and also randomly selects (separate from the random selection of sequence 373) the individual musical note 374 D (the sound produced when the D key that is immediately above the middle C key on a piano is struck). The notes and/or note sequences randomly selected by the software program are chosen from a list of digitally reproduced notes that are stored in memory in module 372, or, if there are a plurality of sound generators in module 372, are chosen from the list of sound generators, or, if a plurality of analog notes are stored in module 372, are chosen from the list of analog notes. Whether the software program randomly selects a single note, a note sequence comprised of two note, a note sequence comprised of three notes, etc. can be randomly determined by the software program. By way of example, the list of digitally reproduced notes maintained in the associated computer memory can correspond to the notes on a piano keyboard. The software program in module 372 can combine selected notes in any desired manner to produce a note pattern and broadcast sound. The manner in which notes are combined to produce a note pattern that is broadcast by module 372 can be randomly determined by the software program. By way of example and not limitation, some ways that the software program can combine the note sequence B, C and the note D selected above to produce a note pattern for broadcast are (1) producing and broadcasting a note pattern in which the three notes B, C, and D are broadcast simultaneously, (2) producing and broadcasting the notes in a pattern in which the notes C-B-D are played one-after-the other, and (3) producing and broadcasting a note pattern in which the C and D notes are played simultaneously followed by the B note. The selected note pattern can be played continuously by repeating the selected note pattern until the sound module 372 is turned off or deactivated, however, the note pattern is typically repeated (or played only once) for a selected limited period of time in the range of one second to sixty seconds. For sake of this discussion, it is assumed that module 372 only plays for a total limited period of time of five seconds the sounds it selects after being activated. Or, after one note pattern is played, the software program can randomly select another different note pattern and produce and broadcast the different note pattern.

In FIG. 34, module 372 has again been activated after it was first activated, first played a note pattern one or more times, and after five seconds stopped playing the note pattern or patterns described with respect to FIG. 33. In FIG. 34, the random selection system randomly chose the individual note middle C, then randomly chose the note F (1^(st) F above middle C on a piano), and then randomly chose the note A (1^(st) A above middle C on a piano). Module 372 can combine the selected notes in any desired note pattern (which pattern can be randomly selected) including, by way of example and not limitation, (1) producing and broadcasting a note pattern in which the three notes C, F, A are broadcast simultaneously, (2) producing and broadcasting the notes in a pattern in which the notes C-F-A are played one-after-the other, and (3) producing and broadcasting a note pattern in which the C and F notes are played simultaneously followed by the A note. Module 372 plays the selected pattern(s) for five seconds and then stops broadcasting the notes.

In FIG. 35, module 372 has again been activated after it was activated, played notes, and after five seconds stopped playing the note pattern(s) as described with respect to FIG. 34. In FIG. 35, the random selection system has chosen the individual note middle C (the middle C on a piano). Module 372 can play the selected note in any desired randomly selected pattern including, by way of example and not limitation, by (1) producing and broadcasting a note pattern in which the note C is broadcast, (2) producing and broadcasting the notes in a pattern in which the note C is played three successive times as C-C-C, and (3) producing and broadcasting a note pattern in which the note C is played simultaneously with the same note C to produce a C sound with a greater volume than if only a single note C is played. Module 372 plays the selected note for five seconds and then stops broadcasting the note.

In FIG. 36, module 372 has again been activated after it was activated, played notes, and after five seconds stopped playing the note pattern(s) as described with respect to FIG. 35. In FIG. 36, the random selection system has chosen several note sequences 379, 380, 381. Sequence 379 is randomly chosen first. The sequence 380 is randomly chosen; then sequence 381. A note sequence comprises two or more notes. Each note in a note sequence can be different from the other notes in the sequence, or, some or all of the notes in a note sequence can be the same as another note in the sequence. The spacing (i.e., the period of time that elapses before a one note in a note sequence is played after another note in the note sequence) can vary as desired. The spacing can be zero if the notes are played simultaneously at exactly the same time, or can be greater than zero. Two notes in a sequence can be identical and played at the same time. If the spacing between two notes is greater than zero, but is still small, a second note can be played while sound from the first note is still being produced and overlaps sound produced when the second note is played. When the time that elapses between the playing of first and second notes in a note sequence is greater than zero, the notes are called successive. The note sequences 379, 380 and 381 are each combinations of two successive notes. Sequence 379 includes two successive different musical notes corresponding in sound to the middle C on a piano and to the D immediately above middle C. The period of time, i.e. the spacing, that elapses between the two successive notes or the notes in any note sequence can vary as desired but usually is fairly short, one-half second or less. Sequence 380 includes two successive different musical notes corresponding to the E and F immediately above the middle C on a piano. Sequence 381 includes two successive musical notes each corresponding to the first G note above the middle C on a piano. Sequence 379 to 381 can be played in succession, one after the other, can be played simultaneously, etc. The software program can randomly alter the spacing between notes in a randomly selected sequence prior to broadcasting the note in the sequence.

The animal toy illustrated in FIGS. 37 and 38 includes a hollow body 382 with opening 384 formed therein. Lid 385 is fixedly or detachably secured to the upper end of body 382 in the manner illustrated in FIG. 37 to seal sound module 383 in opening 384. Module 383 is shorter than opening 384 so that when body 382 is moved back and forth in the directions of arrow E, module 383 slides back and forth (up and down) in opening 384. Module 383 includes a motion sensor that, when module 383 slides in opening 384, detects the movement of module 383 and activates module 383 to produce sound. Module 372 or any other sound module or other kind of module (i.e., a module may, instead of or in addition to producing sound, produce light, produce a scent, produce something that can be tasted, or produce something that can be felt by an animal), can be utilized in place of or in combination with module 383.

The animal toy 386 illustrated in FIG. 39 includes equivalent hollow halves 387 and 388 that are glued or otherwise fastened together along opposing, flat, oval-shaped edge surfaces 387A and 388A to form an egg-shaped core. The shape and dimension of the core and of halves 387, 388 can vary as desired. Half 387 includes flap 389. Half 388 includes flap 390. Each half 387, 388 can include more than one flap. The shape and dimension of each flap can vary as desired. A flap 389 on one half 387 usually, but not necessarily, corresponds in shape and dimension to an opposing flap 390 on another half 388. A flap 389 on one half or portion 387 may not have an opposing flap 390 on another half or portion 388. Or, toy 386 can be molded or otherwise produced with a unitary core having one or more flaps 398 extending outwardly therefrom. Flap 389 is equivalent in shape and dimension to flap 390. When halves 387 and 388 are glued or otherwise fastened together, flaps 389 and 390 can be glued together along surfaces 389A and 390A, can be otherwise fastened together, or need not be secured together. Flaps 389 and 390 are preferably, but not necessarily, pliable and bendable. A layer of felt 391 or other fabric is secured to the outer surface of half 387 in the manner earlier described or in any other desired manner. A layer of felt 392 or other fabric is secured to the outer layer of half 388 in the manner earlier described or in any other desired manner. The felt or fabric is presently preferably not secured to any exposed surface of flaps 389 and 390, but can be if desired. The core and flap(s) or other members extending outwardly from the core are preferably, but not necessarily, shaped and dimensioned such that the assembled toy of FIG. 40 looks like or suggests an animal or other object. The appearance of toy of FIG. 40 suggests a fish.

FIGS. 41 and 42 illustrate construction of an animal toy in which a gas-filled semi-spherical opening 394 is formed in spherical core 393, along with an aperture 396 extending through the core wall to opening 394. Opening 394 can have any desired shape and dimension, as can core 393. Aperture 396 includes countersunk portion 397. If desired, solid thin membrane 395 can extend across the bottom of aperture 396 to help maintain pressure in opening 394 when a layer 399 is compressed onto the outer spherical surface of core 393. Opening 403 is formed in layer 399.

In FIG. 42, squeaker 398 is inserted in aperture 396. Fabric layer 399 is applied before or after squeaker 398 is inserted in aperture 396. If fabric layer 399 is applied to core 393 after squeaker 398 is inserted in aperture 396, squeaker 398 can, if desired, include a plug 419 made of wax or some other material that will melt at 300 degrees F. or some other selected elevated temperature that is greater than ambient temperature, preferably greater than 100 degrees F. Plug 419 prevents air from escaping from opening 394 if compressive pressure is applied to core 393. When layer 399 is applied, adhesive is often applied to core 393 (as earlier described herein) and heat and compressive pressure are applied to layer 399 to bond layer 399 to the outer spherical surface of core 393. When plug 419 is utilized, it is fabricated such that during most of the heating and compression process, the wax prevents air from escaping from opening 394 and prevents the core from collapsing inwardly into opening 394. As the heating and compression process is completed, and the compressive forces are reduced or discontinued, the heat causes the wax plug 419 to melt such that air can travel through squeaker 398 in and out of opening 394. If desired, a small piece of tape can be utilized in place of wax plug 419. The tape adheres to the bottom of and seals squeaker 398. After the heating and compression process for applying layer 399 is complete, a small needle is inserted through the top of squeaker and through squeaker 398 to push the piece of tape off the bottom of squeaker 398 to permit air to flow through the squeaker. Alternatively, a blast of compressed air is directed into the top of squeaker 398 to force the tape off the bottom of the squeaker 398. Any other desired method or apparatus can be utilized to remove the tape from the bottom of the squeaker. If desired, and if the tape and/or wax plug will hold, they tape and/or wax plug can be attached to the top, instead of the bottom, of the squeaker 398.

If fabric layer 399 is applied to core 393 before squeaker 398 is inserted in aperture 396, and membrane 395 is utilized, then membrane 395 functions to prevent air from escaping from opening 394 when core 393 is compressed during the application of layer 399 with compression. After layer 399 is applied, membrane 395 is punctured with a pointed tool before squeaker 398 is inserted. Or, the lower end of squeaker 398 can include a point or cutting edge that punctures membrane 395.

FIGS. 43 and 44 illustrate construction of an animal toy in which a semi-spherical opening 414 is formed in spherical core 404, along with an aperture 415 extending through the core wall to opening 414. The shape and dimension of opening 414 and core 404 need not be semi-spherical or spherical, respectively, and can vary as desired. Aperture 415 includes countersunk portion 416. Opening 417 is formed in and through layer 422. Layer 422 is felt or some other fabric or material. In FIG. 44, squeaker 420 is inserted in aperture 415 and a piece 421 of felt or other fabric or material is used to cover and disguise the location of squeaker 420. Any of the methods or structures described herein or any other desired method or structure can be utilized to insert a squeaker 420 in core 404 or inside opening 414.

FIGS. 45 to 48 illustrate the assembly of an animal toy in accordance with another embodiment of the invention. FIG. 45 illustrates a solid spherical core 421 with a sound module 422 at the center. Core 421 can be formed in any desired manner, but it is presently preferred that module 422 be placed at the center of an empty spherical mold and that a polymer powder be placed in the mold and activated to expand, fill the mold, and encase the module 422 in the manner illustrated in FIG. 45. An aperture(s) can be formed through core 421 extending from the outer surface of core 421 to module 422. In FIG. 46, a layer 423 of felt or other fabric has been applied to the outer spherical surface of the core. Any desired method is utilized to apply and secure the layer 423 to core 421. In FIG. 47, aperture 424 is formed through layer 423 and into core 421. In FIG. 48, squeaker 426 is inserted in aperture 424. The shape and dimension of core 421 can vary as desired.

FIG. 49 illustrates the use of foam, solid rubber, or some other material 229B to embed and anchor the knot 231 or end of a rope 234 in an animal toy 200. Foam 229B includes flat circular end 211A. Toy 200 can take on any shape and dimension, need not include a felt cover, need not include a hollow gas filled compartment 229A (i.e., toy 200 can be completely solid with knot 231 embedded therein), etc.

Another embodiment of the invention is illustrated in FIG. 52 and includes a hollow resilient toy 450, preferably provided with a fabric cover 463 that is applied to a core using any of the methodologies recited herein or using any other desired application procedure. Cylindrical opening 460 is open at both ends, extends completely through toy 450, and is sealingly continuous along its length such that water or another liquid flowing through cylindrical opening 460 from one end of opening 460 to the other end of opening 460 will not leak into the hollow interior of toy 450.

Member 451 is shaped and dimensioned to be slidably inserted in opening 460, preferably, although not necessarily, such that ends 415A and 451B extend outwardly from opening 460 and toy 450.

The toys, or portions thereof, illustrated in FIGS. 52 to 58 pertain to a toy 450 having a generally spherical shape. The shape and construct of a toy 450 can, however, vary as desired, although a toy susceptible to being manufactured in two separate halves which can be joined along seam lines or edges to form a hollow buoyant toy is preferred with respect to the toys discussed in connection with FIGS. 50 to 59. In one embodiment of the invention, the toys set forth and discussed with respect to FIGS. 50 to 59 are configured to float in water. In another embodiment of the invention, the toys set forth and discussed with respect to FIGS. 50 to 59 are not configured to float, and sink in water.

In one method for manufacturing toy 450, a pair of identical resilient hollow halves are produced. One half 450A is illustrated in FIGS. 53 and 55. The other half 450B is illustrated in FIG. 56. Half 450A is identical to half 450B except that half 450B (FIG. 56) includes a pair of halves 484 and 483. In FIG. 55, half 450A is illustrated with fabric cover 463 secured to the exterior of half 450B. In FIG. 56, half 450B is illustrated with fabric cover 463 secured to the exterior of half 450B.

Half 450A includes a partial interior semi-cylindrical channel 460A bounded by spaced apart parallel, elongate edges 461 and 462. Arcuate edge 466 extends from one end of channel 460A to the other end of channel 460A. Arcuate edge 467 extends from one end of channel 460A to the other end of channel 460A. Opening 464 extends around channel 460A.

Half 450B includes a partial interior semi-cylindrical channel 460B bounded by spaced apart parallel, elongate edges 461B and 462B. Arcuate edge 466B extends from one end of channel 460B to the other end of channel 460B. Arcuate edge 467B extends from one end of channel 460B to the other end of channel 460B. Opening 465 extends around channel 460B.

When halves 450A and 450B are joined, half 450A is attached to half 450B such that edge 462 is in registration with and attached to edge 462B; such that edge 461 is in registration with and attached to edge 461B; such that edge 466 is in registration with and attached to edge 466B; and, such that edge 467 is in registration with and attached to edge 467B.

After halves 450A and 450B are joined to form a toy core, channels 460A and 460B collectively, along with openings through cover 463, form cylindrical opening 460 extending through toy 450. The portion of opening 460 extending through the core form a continuous sealed channel such that water or another fluid passing through opening 460 can not enter the hollow interior of the core, which hollow interior or volume is generally spherically shaped (with the exception of opening 460 extending therethrough) and collectively includes openings 464 and 465.

Fabric cover 63 is secured to the outer generally spherical surface of the core to produce toy 450. Any of the methods described herein, or any other desired method, can be utilized to affix cover 63 to the exterior of the toy core.

In an alternate embodiment of the invention, a pair of identical halves 490 (FIG. 54) are produced and each include circular edges 491 and 493, and semi-spherical opening 495 extending around a partial cylindrical channel member 492 formed therein. A cylindrical opening 494 extends through the interior of member 492. Halves 490 are jointed together such that edges 491 of each half are in registration and attached and such that edges 493 of each half are in registration and attached. Accordingly, when halves 490 are so attached to each other, the resulting core has the same general shape and dimension of the core produced when halves 450A and 450B are adjoined.

In the embodiment of the invention illustrated in FIG. 55, a water absorbent fabric member 470 is provided and includes an intermediate portion 473 extending through opening 460 and between a first knotted end 471 and a second knotted end 472. In FIG. 55, member 470 comprises a length of rope, although any other desired fabric or other member can be utilized. Member 470 is produced and installed in toy 450 by taking a length of rope, and typing a knot in one end 471 of the rope. The diameter of the rope is less than the diameter of opening 460 so that the rope can be threaded through opening 460. is large enough to not fit into opening 460. The knot formed in end 471 is large enough to not fit into opening 460. The portion of the rope extending from the knot formed in end 471 is threaded through opening 460, and a knot is tied in the other end 472 of the rope. The knot in end 472 is also too large to fit into opening 460. After member 470 is installed, the shape and dimension of member 470 and of toy 450 (including the hollow, gas filled area 464, 465 formed in the toy) is such that even after member 470 and/or the fabric cover 463 absorb to their capacity the maximum amount of water, toy 450 will still remain buoyant and float. Member 470 preferably, but not necessarily, is softer and less rigid than the core of toy 450. Member 470 can also, if desired, be pliable as is, for example, a soft cotton rope. Member 470 can also, if desired, be readily deformed in many directions as is, for example, a soft cotton rope. Providing a soft, pliable and readily deformed member 470 reduces the risk of injury to a dog or other animal using toy 450.

In the embodiment of the invention illustrated in FIG. 56, an ingestible food composition 475 is inserted in opening 460 in place of, or in conjunction with, member 470. Composition 475 includes intermediate portion 478 extending through opening 360 and includes ends 476 and 477 extending outwardly from opening 460 and toy 450. Composition 475 is edible and preferably, but not necessarily, is softer and less rigid than the core of toy 450. Composition can also, if desired be pliable and/or can be readily deformed in many directions. Providing a soft, pliable and readily deformed composition 475 reduces the risk of injury to a dog or other animal using toy 450.

In the embodiment of the invention illustrated in FIG. 57, a sound module 482 is inserted in opening 460 in place of, or in conjunction with, member 470 and composition 475. A first end 483 of a first rope member is affixed to one end of module 482. The second end 484 of the first rope member is located outside of toy 450. A knot 485 is tied in the second end 484 and has a width greater than the diameter of opening 460. The first end of a second rope member is affixed to the other end of module 482. The second end 486 of the second rope member is located outside of toy 450. A knot 487 is tied in the second end 486 and has a width greater than the diameter of opening 460. In one embodiment of the invention, knot 487 is tied in end 486 and end 484 is threaded from one side of toy 450 through opening 460 to the opposite side of toy 450. End 484 is then utilized to pull module 482 into opening 460 to the position illustrated in FIG. 57. Knot 485 is then tied in end 484 to secure module 482 in opening. If desired, the diameter of module 482 can be equivalent to or slightly larger than the diameter of opening 460 so that module 482 must be force fit into opening 460. This is particularly useful when the cylindrical wall of opening 460 is resilient. FIG. 58 illustrates one embodiment 488 of a sound module in which the sound module has a shape and dimension generally equivalent to that of opening 460 is covered with fabric. The fabric at ends 490 and 491 is generally equivalent to the fabric 463 (FIG. 55) covering the core such that once module 488 is inserted in opening 460, ends 490 and 491 are flush with and blend in with the fabric 463 on the exterior of the core of toy 450. The shape and dimension of sound module 488 can vary as desired, as can that of opening 460. In one embodiment of the invention, the middle, or interior, part of opening 460 has a larger diameter or width than do the end parts of opening 460 that are near the exterior of toy 450. Said middle, or interior, part is slightly larger than a specialty sound module made to fit in said middle part. The specialty sound module is forced through an end of opening 460 and into the interior part of opening 460.

A sound module 488 can be designed to be activated by motion, by pressure, by a radio signal that is received by the module 488, or by any other desired mechanism. More than one sound module 488 can be included in a toy 450. A module 488 can produce sound electronically, as the result of air flowing over or through the module, etc. The method of the invention illustrated in FIG. 50 includes the step 430 of providing a 1^(st) resilient hollow toy half with a 1^(st) open partial interior channel, includes the step 431 of providing a 2^(nd) resilient hollow toy half with a 2^(nd) open partial interior channel, includes the step 432 of assembling the 1^(st) and 2^(nd) toy halves with partial interior channels in registration to form a resilient hollow toy core with a sealed open-ended channel extending therethrough, includes the step 433 of applying a fabric cover to the exterior of the toy using temperature, pressure, and/or adhesive, includes the step 434 of providing a soft water absorbent member shaped and dimensioned to extend through and include ends outside the sealed channel such that the toy will float when the soft member is water logged, includes the step 435 of inserting the soft, water absorbent member in the sealed channel such that the ends of the water absorbent member extend outside the sealed channel, includes the step 436 of providing a swimming pool, includes the step 437 of throwing the toy in the swimming pool to float and to absorb water, and includes the step 438 of allowing a dog to retrieve the floating toy from the swimming pool.

The method of the invention illustrated in FIG. 51 includes the step 440 of providing a 1^(st) resilient hollow toy half with a 1^(st) open partial interior channel, includes the step 441 of providing a 2^(nd) resilient hollow toy half with a 2^(nd) open partial interior channel, includes the step 442 of assembling the 1^(st) and 2^(nd) toy halves with partial interior channels in registration to form a resilient hollow toy core with a sealed open-ended channel extending therethrough, includes the step 443 of applying a fabric cover to the exterior of the toy using temperature, pressure, and/or adhesive, includes the step 444 of providing a soft ingestible food member shaped and dimensioned to extend through and include ends outside the sealed channel such that the toy will float, includes the step 445 of inserting the soft food member in the sealed channel such that ends of the food member extend outside the sealed channel, includes the step 446 of providing a swimming pool, includes the step 447 of throwing the toy in the swimming pool to float, and includes the step 448 of allowing a dog to retrieve the floating toy from the swimming pool and eat the food member.

The method of the invention illustrated in FIG. 59 includes the step 500 of providing a 1^(st) resilient hollow toy half with a 1^(st) open partial interior channel, includes the step 501 of providing a 2^(nd) resilient hollow toy half with a 2^(nd) open partial interior channel, includes the step 502 of assembling the 1^(st) and 2^(nd) toy halves with partial interior channels in registration to form a resilient hollow toy core with a sealed open-ended channel extending therethrough, includes the step 503 of applying a fabric cover to the exterior of the toy using temperature, pressure, and/or adhesive, includes the step 504 of providing a sound module shaped and dimensioned to extend in the sealed channel such that the toy will float, includes the step 505 of inserting the sound module in the sealed channel, includes the step 506 of providing a swimming pool, includes the step 507 of throwing the toy in the swimming pool to float and to absorb water, and includes the step 508 of allowing a dog to retrieve the floating toy from the swimming pool.

An alternate embodiment of the animal toy of the invention is illustrated in FIGS. 60 to 68. The animal toy can comprise a dog toy, cat toy, or toy for any other desired animal.

In FIG. 60 a squeaker assembly 511 is mounted in the spherical wall of a hollow elastic, resilient ball 510. Assembly 511 is adhesively secured, force fit, or otherwise secured in the wall of ball 510. The spherical wall includes outer surface 512. The outer surface of upper end 530 of unit 514 (FIG. 70) is generally flush with the outer surface 512 of ball 510.

FIGS. 61 and 62 further illustrate the integration of squeaker assembly 511 in the wall of ball 510. In operation of the animal toy 510, when ball 510 is resiliently compressed, air is forced outwardly through the assembly 511. When air is forced outwardly through assembly 511, it causes a reed housed within assembly 511 to vibrate and produce sound that is audible to the animal playing with the toy. After the ball 510 is compressed and released, the wall of ball 510 resiliently returns to its original spherical shape illustrated in FIG. 60. When ball 510 returns to its original shape, air is drawn into the ball through assembly 511. When air is drawn inwardly into the hollow in side ball 510, it passes over the reed and causes the reed to vibrate and produced sound.

The cylindrical squeaker unit that houses internally the reed is identified by reference character 516 in FIGS. 63 and 64. Air flows into unit 516 through an opening in end 516B and out from unit 516 through an opening in end 516A, or vice versa. Cylindrically shaped leg 517 of unit 516 is sized to be slidably received by and seat in cylindrically shaped aperture 518 formed in component 514 (FIG. 66).

FIGS. 63 and 64 are exploded views illustrating the squeaker assembly 511. Some of the principal components of assembly 511 are illustrated in greater detail in FIGS. 65 to 68.

Component 515 includes upper end 522, lower end 520, internal thread 524, and opposing, spaced apart circular ledge surfaces 521 and 523.

Component 514 is illustrated in greater detail in FIGS. 65 and 66 and includes upper end 530, lower end 531, external thread 532, cylindrical aperture 518, cylindrical aperture 537, pie-shaped aperture 535, cylindrical aperture 537, and slot 534. Aperture 537 opens into aperture 518. Aperture 518 extends along the greater portion of the length of component 514.

Component 513 is illustrated in greater detail in FIGS. 67 and 68 and includes cylindrically shaped leg 540, a front surface with raised arrow 545 formed thereon, rear surface 544, slot 541, and apertures 542 formed through component 513.

Assembly of the squeaker unit 511 is accomplished as follows.

First, end 516A and cylindrically shaped leg 517 of squeaker 516 is slidably inserted and seated in aperture 518.

Second, component 513 is seated in aperture 546 (FIG. 65) of component 514 by rotatably inserting leg 540 in cylindrical aperture 537. When apertures 542 are in registration with pie-shaped openings 535, air can flow through openings 535 and squeaker 516. When component 513 is rotated in the manner indicated by arrows 550 and openings 542 are no longer in registration with openings 535, then openings 535 are blocked and air can no longer flow through openings 535 and squeaker 516.

Third, internal thread 524 of component 515 is turned onto external thread 532 of component 514. This completes the assembly of squeaker assembly 511.

An appropriately shaped opening 512A is formed in the wall of ball 510 and squeaker assembly 511 is inserted therein. Alternatively, a ball 510 is molded or otherwise formed around assembly 511.

In operation, as noted above, component 513 is manually rotated in the appropriate direction 550 to insure that openings 542 are positioned over apertures 535. This permits air to flow through apertures 535 and squeaker assembly 511 such that noise is produced. In the event it is desired to prevent squeaker assembly 511 from producing sound, component 513 is manually rotated in the appropriate direction 550 to move openings 542 away from apertures 535 such that apertures 535 are covered by the portion of component 513 that does not have openings 542 formed therethrough. This blocks the flow of air through apertures 535 and squeaker assembly 511 and prevents assembly 511 from producing sound. Component 513 can be rotated by inserting the edge of a coin in slot 541 and manually turned the coin, and therefore component 513 in the directions indicated by arrows 550 (FIG. 68).

The edge of a coin can be inserted in slot 534 and the coin turned manually to unthread component 514 from component 515. When component 514 is removed from component 515, squeaker 516 is also removed. This leaves an internally threaded 524 cylindrically shaped opening that extends through hollow component 515. Air flows into and out of ball 510 through this opening without producing sound.

After component 514 is removed from component 515, the squeaker 516 can, if desired, be removed from component 514 and component 514 reinstalled in component 515. In this case, air flows into and out of ball 510 through apertures 537 and 518 (FIGS. 65, 66) without producing sound. In an alternate embodiment of the invention, aperture 537 or 518 is shaped and dimensioned to produce sound when air flow therethrough.

After component 514 is removed from component 515 and squeaker 516 is removed, a new squeaker can be inserted in component 514 before it is threaded back into component 515. This new squeaker may produce a sound equivalent to or different from the sound produced by squeaker 516.

Components 513, 514, 515 can be fabricated from any desired material but presently consist of a rubber or plastic material. This material preferably is hard, durable and substantially rigid and serves to protect the squeaker 516 that is housed in assembly 511.

FIGS. 60 to 68 illustrate one manner in which the functioning of a squeaker 516 can be controlled. Another approach is to utilized a stopper, similar in function to the stopper in a sink or bathtub that is used to prevent water from flowing out of the sink or bathtub. The stopper opens and closes the drain, and can consist of a simple rubber plug that is manually placed in and removed from the drain, can consist of a spring loaded stopped the is pressed in place to close the drain and is pressed again to release the stopper upwardly and open the drain. A similar stopper device can be used, for example, in opening 537 or 546 (FIG. 65), or in the opening at one end 516A, 516B of a squeaker 516.

Another approach which can be used to control the function of a squeaker 516 is to provide a squeaker which can be inserted in a toy to produce a squeak when the toy is compressed (or is moved, for example, thrown), and which can be removed from the toy so the toy will not making a squeaking sound when an animal plays with the toy.

A further approach which can be used to control the function of a squeaker 516 is to provide a squeaker which has a reed structure that vibrates and produces sound when air moves over the reed. The squeaker also include a member which can be selectively positioned to be spaced away from the reed so the reed vibrates, or, to be in contact with the reed to prevent the reed from vibrating.

Still another approach which can be used to control the function of a squeaker 516 is to provide an electronic squeaker which includes an on-off switch and a motion detector.

When the switch is on and the squeaker (i.e., the animal toy in which the squeaker is mounted) moves, the motion detector generates signals to a control unit which causes a sound producing assembly in the toy to produce sound.

When the switch is off, the sound producing assembly will not produce noise when the animal toy is moved. In another version of this approach, the switch has additional settings other than on-off (or a second switch can be provided). At one of the additional settings the sound producing assembly produces a first sound, at another of the additional settings the sound producing assembly produces a second sound different from the first sound.

Still a further approach which can be used to control the function of a squeaker 516 is to provide an opening in the wall of an animal toy—ball 510 for example—in which a squeaker is slidably mounted for movement between two operative positions.

In the first operative position, the squeaker is sealingly seated in the opening so that when the ball 510 is compressed, air travel from the inside of the ball 510 outwardly through the squeaker. The air flows over a vibrating reed in the squeaker 516 and sound is produced.

In the second operative position, the squeaker is slidably displaced in the opening such that air can flow through the opening and around the squeaker. In this manner, a vent opening is formed and air flows out of (and into) the toy through the vent opening and bypasses the squeaker. Since the air flow bypasses the squeaker, the squeaker does not produce sound.

In another application of this approach, a squeaker is permanently mounted in a fixed location in a toy, and the vent opening is formed at a separate location in the toy. Means is provided to open and close the vent opening. When the vent opening is open, air flows through the vent opening and not through the squeaker and the squeaker is rendered inoperable. When the vent opening is closed, air flows through the squeaker when the ball 510 is compressed or is released (and resiliently returns to its pre-compression original configuration) and the squeaker produces sound.

The manner in which a squeaker produces sound can vary as desired. Squeakers with reeds and with electronically controlled sound assemblies are, by way of example and not limitation, noted above. Another squeaker configuration can simply use an appropriately shaped opening which produces sound when air flows through the opening at a selected flow rate. Or a squeaker may include a component slidably mounted in the squeaker such that when the component slides from one position to another, air flowing over or through the component produces sound.

FIGS. 78 and 79 illustrate a system to inductively charge a battery in a dog toy, cat toy, or other animal toy without requiring the use of physical wires that extend between the charging source and the battery that is being charged. The battery is housing and concealed in the animal toy so that it is automatically charged when it is seated in a charging unit. The battery provides motive power to a microprocessor or other electronic or electrical device that is housed in or mounted on the animal toy. The battery preferably is permanently fixedly mounted inside the toy to prevent an animal from readily accessing the battery, but can, if desired, be removably mounted in the toy.

FIG. 78 illustrates one inductive charging system that can be utilized in the practice of the invention, although any desired inductive charging system can be employed.

The charging system of FIG. 78 includes a conventional 120 volt, 60 cycle source 610 connected to a rectifier 560 to drive oscillator 561. Oscillator 561 can, by way of example and not limitation, provide a high frequency AC signal of 30,000 cycles per second. This high frequency signal can vary as desired depending on the particular application.

A transmission coil includes first and second coils 613, 614 with adjacent ends connected at 615 to lead 616 from oscillator 561. The outer end of each coil 613, 614 is connected to output lead 617, 618, respectively, to produce a two phase oscillator. Each coil can include an iron core (not shown). A single phase transmission coil can, if desired, be utilized.

Secondary receiving coil 621 can also include an iron core (not shown). Coil 621 is spaced apart from coils 613, 614 a distance which permits coil 621 to couple with the electromagnetic field produced by coils 613, 614. Coils 613, 614 and coil 621 can be resonantly tuned to a selected high frequency by using capacitors C1, C2 and by using capacitor C3, respectively. The distance between coil 621 and each of coils 613, 614 ordinarily is less than one wave length of the selected high frequency so that inductive coupling occurs.

Secondary coil 621 connects to regulator 563. Regulator 563 connects to AC to DC converter 562. Converter 562 generates a DC charging signal on line 626 to a rechargeable DC battery 627. Battery 627 is recharged by using a constant current. The regulator 563 permits charging up to about eighty percent. The charging signal is then converted to a constant voltage or trickle type charge.

Rate limiter 564 interfaces between regulator 563 and a sensor 629 in battery 627; and, also interfaces between AC to DC converter 562 and sensor 629.

Rate limiter 564 is responsive to one or more of the three parameters of temperature, voltage and gas pressure in battery 627. Inputs for each of these three parameters is provided to rate limiter 564 as indicated schematically by input lines 630, 631, 632.

In FIG. 78, the induction charger 572 includes coils 613, 614 and the various components (rectifier 560, oscillator 561, capacitor C2, etc.) to the left of coils 613, 614. The battery charging system 573 includes coil 621 and the various components (capacitor C3, regulator 563, battery 627, etc.) to the right of coil 621.

FIG. 79 illustrates one possible specific application of an inductive charging system in an animal toy 565. The induction charger 572, including coils 613 and 614, is mounted in induction charger base 570. The battery charging system 573, including coil 621, is housed in animal toy 565. Semi-cylindrical detent 571 is formed in induction charger base 570 and is shaped and dimensioned to receive, conform to, and seat at least the bottom potion of animal toy 565 such that coil 621 is positioned sufficiently close to coils 613, 614 to permit coil 621 to inductively charge battery 627. Battery 627 and the other portions of battery charging system 573 are housed in animal toy 565. Battery 627 provides motive power for a LED or other light source 567, squeaker 568, or other electrically powered component that is mounted in toy 565. In one embodiment of the invention, a manually operable switch (not shown) is mounted in toy 565 and can be used to turn an electric light 567 or electrically operable squeaker 568 on and off. Electric cord 574, when plugged into a wall outlet, functions as a conventional 120 volt, 60 cycle source, is equivalent to source 610, is connected to rectifier 560, and drives oscillator 561.

As would be appreciated by those of skill in the art, the battery charging system 573 can be mounted in any of the animal toys set forth herein, or in any other desired animal toy. And, an induction charger base 570 can be appropriately configuration to receive a desired animal toy such that an induction charger in base 50 can couple with system 573 and charge a battery therein.

In use, animal toy 565 is used to play with a dog or other animal. When the battery 627 in toy 565 weakens, toy 565 is seated in base 570 with coil 621 adjacent coils 613 and 614. Cord 574 is plugged into a 120 volt wall outlet to provide current flow into rectifier 560 and, subsequently, to produce via coils 613, 614 and electromagnetic field 23 to inductively charge battery 627 via coil 621 and the remaining components of the battery charging system 573.

Since in FIG. 79, toy 565 houses electronic components comprising the battery charging system 573, it is preferred that the core of toy 565 encase system 573 and be fabricated from rubber or some other material that is difficult for a dog or other animal to chew through. One example of such a material is the rubber used in the EXTREME KONG™ dog chew toy. Such a core can, as is depicted a variety of times herein, be covered or coated with a fabric or some other material(s). When a toy 565 is being fabricated, system 573 can, for example, be placed in a mold prior to injecting the mold with a material which forms the core of the toy. In this manner, the material which forms the core of the toy encases and conceals system 573. In another manufacturing scenario, the core of the toy is first molded or otherwise formed, after which system 573 is mounted on the toy, preferably on the interior of the toy.

In one embodiment of the invention, a microprocessor is mounted in an animal toy and can be reprogrammed to change, for example, the color of a light that is produced by a light source mounted in the toy. One way the microprocessor can be reprogrammed is by depressing and releasing a spring loaded button in a selected sequence. The sequence might comprise the number of time the button is depressed. It might comprise pressing and releasing the button a selected number of times, pausing for a selected period of time, and then again depressing and releasing the button a selected number of times. The spring loaded button is mounted in the animal toy.

In another embodiment of the invention, a microprocessor mounted in an animal toy is reprogrammed by sharply tapping the toy at a selected location, or, is automatically reprogrammed when an animal compresses the toy by squeezing the toy with in its mouth, between its paws, etc.

In a further embodiment of the invention, the induction charger base 570 has the shape and dimension of a pen, the coil(s) 613, 614 are located in the nose of the pen, and the animal toy has a port or opening shaped and dimensioned to receive the nose of the pen. Coil 621 is located adjacent the port. When the toy is not being used, the battery 627 in the animal toy is charged by inserting the nose of the pen in the port such that coil(s) 613, 614 are adjacent coil 621.

FIG. 71 illustrates a gravure-fabric animal toy constructed in accordance with another embodiment of the invention and generally indicated by reference character 640. A preferred method of fabricating toy 640 comprises molding a pair of hollow oval elastomer core halves 60A, 60B which each have a flat continuous seam face 640B (FIG. 72) that extends along an oval path. The seam faces 640B of each core half are adhesively or otherwise joined along oval seam line 640A (FIG. 71) to form a hollow generally egg-shaped elastomer core. Each half 60A, 60B has a shape and dimension that is generally equivalent to that of the other half. FIG. 72 illustrates core half 60A. The semi-ovular shape of half 60A partially circumscribes hollow volume 648.

A portion of the exterior of each half 60A, 60B includes a molded gravure surface 641, 641A which includes raised lines, points, or spaces and also includes incised lines, points, or spaces. As can be seen in FIG. 72, gravure surface 641 includes a plurality of ridges. A portion of the exterior of each half also includes a smooth arcuate surface 647 which receives one or more pieces of fabric 642. The shape and dimension and contour of surface 647 can vary as desired, but surface 647 typically is flat or curved and is smooth to facilitate the application of fabric 642. Fabric 642 typically is adhered to surface 647 with adhesive, and, can further be heated or compressed against surface 647 to better secured fabric 642 to surface 647. The kind of fabric 642 utilized can vary as desired. In one embodiment of the invention fabric 642 is felt. In another embodiment of the invention fabric 642 comprises a smooth, woven nylon material. The cover of a baseball comprises a pair of pieces of leather or other material that are stitched together along a seam line. Each piece of material has an equivalent shape and dimension and has rounded ends that are larger than the intermediate portion of the piece so that the two pieces interfit on and cover the surface of the baseball. In like fashion, the shape and dimension of the perimeter 645 of gravure surface 641, 641A on the assembled toy 640 is generally equivalent to the shape and dimension of the perimeter 643 of surface 647 on the assembled toy 640.

A seam 644 extends intermediate the perimeter 645 and the perimeter 643. In one embodiment of the invention, the seam 644 comprises an elastomer tape that is applied after fabric 642 is applied to surface 647. The elastomer tape can, if desired, be heated and compressed to more completely fill any space between perimeters 645 and 643 and to make the outer surface of the tape generally flush with the outer surfaces 641, 641A and with the outer surface of fabric 642.

FIG. 73 illustrates a gravure-fabric animal toy constructed in accordance with another embodiment of the invention and generally indicated by reference character 650. A preferred method of fabricating toy 650 comprises molding a pair of hollow oval elastomer core halves 650A, 650B (FIG. 74) which each have a flat continuous seam face that extends along a circular path. The seam faces of each core half are adhesively or otherwise joined along circular seam lines 660, 660A to form a hollow generally doughnut-shaped elastomer core. Each half 650A, 650B has a shape and dimension that is generally equivalent to that of the other half.

FIG. 74 is a section view of toy 650 taken along section line 74-74 in FIG. 73. Halves 650A, 650A circumscribe hollow volume 661 (FIG. 74). As is illustrated in FIG. 73, each half 650A, 650B has a semi-cylindrical cross section.

A portion of the exterior of each half 650A, 650B includes a pair 654-655 or 656-657, respectively, of molded gravure surfaces which each include raised lines, points, or spaces and also includes incised lines, points, or spaces. In particular, each surface 654 to 657 includes a plurality of spaced apart raised dimples 657, 658. Two areas of the exterior of each half 650A, 650B also each include a smooth arcuate surface 665, 666 which receives one or more pieces or layers of fabric 652, 653, 664. The shape and dimension and contour of each surface 665, 666 can vary as desired, but surfaces 665, 666 typically are each flat or curved and are smooth to facilitate the application of fabric 652, 653, 664.

Each fabric piece or layer 652, 653, 664 typically is affixed to a surface 665, 666 with adhesive or another fastening system, and, can further be heated or compressed against surface 665, 666 to better secure fabric 652, 653, 664 to surface 665, 666. The kind of fabric 652, 653, 664 utilized can vary as desired. In one embodiment of the invention fabric 652, 653, 664 is felt. In another embodiment of the invention fabric 652, 653, 664 comprises a smooth, woven nylon material.

An inner seam 662 and outer seam 663 extends between each pair 652-664 of adjacent fabric layers. As is illustrated in FIG. 78, each seam 662, 663 comprises a pair of adjacent outwardly projecting flanges 667, 668 that are integrally formed as part of a halve 650B, 650A, respectively, when the halves 650B, 650A are molded. Each flange 667, 668 extends along an arcuate path on the inside or outside of toy 650. Seams 662, 663 function as lines of demarcation between fabric layers 652-664. Instead of utilizing flanges 667, 668 to form a line of demarcation, the elastomer tape described with respect to FIGS. 71 and 72 can be utilized to form a seam. If desired, detents 684, 685 (FIG. 78) can be formed adjacent flanges 667, 668. Each detent 684, 685 extends along an arcuate path and permits the edge of a piece of fabric 653 to be “tucked into” the detent 684, 685 to better seal the edge in position adjacent a seam 662.

FIG. 75 illustrates an animal toy 690 constructed in accordance with another embodiment of the invention. Any desired method can be utilized to construct toy 690 and toy 690 can be solid, hollow, filled with foam, etc. It is presently preferred, however, that toy 690 be hollow and constructed in a manner similar to that earlier described with respect to the toys in FIGS. 71 to 74; namely, a pair of hollow halves are molded and are affixed together along a peripheral seam line (not shown) which extends through the head 691, neck 692, body, and tail 693 of toy 690. The seam extends between nostrils 698, 699 and eyes 700, 701 and bisects outwardly extending fins 694.

A portion of the exterior of each half of toy 690 includes molded gravure surfaces which each include raised lines, points, or spaces and also includes incised lines, points, or spaces. In particular, each half includes a nostril 698 or 699, an eye 700 or 701, part of a fin 694, etc. One area on the exterior of each half includes a smooth arcuate surface (not visible) which receives one or more pieces or layers of fabric 695. The shape and dimension and contour of each such fabric-receiving surface can vary as desired, but the surface typically is flat or curved and is to facilitate the application of fabric 695. In FIG. 75, fabric 695 extends substantially around the ovular body of toy 690. The exterior surfaces of toy 690 not covered by fabric 695 comprise molded gravure surfaces. Accordingly, the exterior surfaces of the head 691, neck 692, and tail comprise molded gravure surfaces. Likewise, fins 694 comprise molded gravure surfaces. If desired, toy 690 can include legs 696, 697.

Each fabric piece or layer 695 typically is affixed to an exterior surface with adhesive or another fastening system, and, can further be heated or compressed against the exterior surface to better secure fabric 695 to the surface. The kind of fabric 695 utilized can vary as desired. In one embodiment of the invention fabric 695 is felt. In another embodiment of the invention fabric 695 comprises a smooth, woven nylon material.

Seams 702 and 703 each extend between fabric 695 and adjacent molded gravure surfaces. Each seam can simply comprise an edge of fabric 659, can comprise one or more molded outwardly projecting flanges comparable to flanges 667, 668 (FIG. 78), or can comprise a strip of elastomer tape similar to the elastomer tape 644 described with respect to FIGS. 71 and 72. If desired, detents similar to detents 684, 685 can comprise part or all of a seam 702, 703. A peripheral edge of fabric 695 can be tucked into such a detent 684, 685.

FIG. 74 illustrates an animal toy 686 constructed in accordance with another embodiment of the invention. The toy 686 includes a finned, football-shaped body 675 and pliable polymer tails 683 attached to body 675. Any desired method can be utilized to construct body 675 and body 675 can be solid, hollow, filled with foam, etc. It is presently preferred, however, that body 675 be substantially hollow and constructed in a manner similar to that earlier described with respect to the toys in FIGS. 71 to 72; namely, a pair of hollow halves are molded and are affixed together along a peripheral seam line (not shown).

A portion of the exterior of each half of toy 690 includes molded gravure surfaces which each include raised lines, points, or spaces and also includes incised lines, points, or spaces. In particular, each half includes a portion of nose 677, includes a portion of end 682, and includes one or more outwardly projecting fins 678, 679, 680, and 681. One area on the exterior of each half includes a smooth arcuate surface (not visible) which receives one or more pieces or layers of fabric 676. The shape and dimension and contour of each such fabric-receiving surface can vary as desired, but the surface typically is flat or curved and is to facilitate the application of fabric 676. In FIG. 74, fabric 676 extends substantially around the ovular body of toy 690. The exterior surfaces of toy 690 not covered by fabric 695 comprise molded gravure surfaces. Accordingly, nose 677, end 682, and fins 678, 679, 680, comprise molded gravure surfaces.

Each fabric piece or layer 676 typically is affixed to an exterior surface with adhesive or another fastening system, and, can further be heated or compressed against the exterior surface to better secure fabric 676 to the surface. The kind of fabric 676 utilized can vary as desired. In one embodiment of the invention fabric 676 is felt. In another embodiment of the invention fabric 676 comprises a smooth, woven nylon material.

Seams 705, 706, and 707 each extend between fabric 676 and an adjacent molded gravure surface. Each seam can simply comprise an edge 688 (FIG. 75) of fabric 676, can include one or more molded outwardly projecting flanges 687 (FIG. 75) comparable to flanges 667, 668 (FIG. 78), or can include a strip of elastomer tape similar to the elastomer tape 644 described with respect to FIGS. 71 and 72. If desired, detents similar to detents 684, 685 can comprise part or all of a seam 705 to 707. A peripheral edge of fabric 695 can be tucked into such a detent 684, 685.

As would be appreciated by those of skill in the art, any of the manufacturing processes described herein can, along with any other desired manufacturing process, be utilized to fabricate any of the toys described herein. Seam structures, wall structures, materials, attachment systems, etc. described herein can be, if desired, be utilized on or with any of the toys described herein.

FIGS. 79 to 81 illustrate a squeaker assembly in which a squeaker is housed in a protective casing 711 that is integrally formed in the spherical wall of a hollow elastic, resilient ball 710. The spherical wall includes outer surface 712. Casing 711 spaces the squeaker away from outer surface 712. Protective casing 711 houses assembly 511 earlier described herein. As noted, cylindrical squeaker unit 516 is housed in assembly 511. Consequently, in FIG. 79, squeaker unit 516 is spaced apart from outer surface 712, which makes it difficult for a dog or other animal to access squeaker unit 516. Umbilical opening 713 extends from outer surface 712 completely through the wall of toy 710 to assembly 511 to enable air to flow through umbilical to and from assembly 511. If necessary, a secondary umbilical opening 715 (FIG. 79) can extend from assembly 511 to the hollow air-filled interior of ball 710 to put assembly 511 and the squeaker unit 716 therein in fluid communication with the interior of ball 710 so that air can flow from the exterior of ball 710 through umbilical opening 713, through assembly 511 and into the interior of ball 710, or vice-versa. As would be appreciated in the art, and as is the case with various other hollow toys described herein, the hollow toy in which casing 711 is utilized need not have a spherical shape, but can have any desired shaped and dimension.

The location and orientation and shape and dimension of casing 711 with respect to the wall of a toy 710 can vary as desired. FIG. 80 illustrates a casing 711A having a different shape and dimension and orientation than casing 711. Umbilical opening, or conduit, 713A extends completely through the wall of toy 710 and puts casing 711A in fluid communication with ambient air on the exterior of toy 710. During the process of manufacturing toy 710, an outwardly extending, upstanding nub 714 can be formed on the exterior surface 712 to enable an individual to locate by touch the nub 714 after the exterior surface 712 is covered by a layer of fabric. The individual uses his or her sense of touch to feel and locate the nub through the layer of fabric. The ability to locate by touch nub 714 can be advantageous when (1) a thin film covers or at some point along opening 713 blocks opening 713 and (2) the film needs to be pierced to opening 713 so air can flow therethrough. Nub 714 can comprise the thin film or can be located adjacent opening 713.

When protective casing 711 encloses assembly 511, casing 711 and assembly 511 provide, in essence, a double layer of protection for squeaker unit 516. As would be appreciated by those of skill in the art, assembly 511 need not be utilized, and squeaker unit 516 can simply be housed in casing 711 such that umbilical opening 713—and, if necessary, secondary opening 715—permit air to flow through squeaker unit 516.

In one embodiment of the invention, toy 710 is produced by forming a pair of mirror image halves and gluing or otherwise fastening the two halves 710A, 710B together to house assembly 511. The top and bottom halves of the toy are each formed from a compressibly elastically deformable hollow thin-walled elastomer. The top half 710A of toy 710 is illustrated in FIG. 81 as a section view of toy 710.

The top half 710A and bottom half 710B each include a supplemental semi-spherical exterior surface which, when the top and bottom halves are joined, comprises one half of exterior surface 712. In FIG. 81, this supplemental surface is indicated by reference character 712A.

The top half 710A and the bottom half 710B each include a supplemental semi-cylindrical portion which, when the top 710A and the bottom 710B halves are joined, comprises one half of umbilical opening 713. In FIG. 81, this supplemental semi-cylindrical portion is indicated by reference character 713A. When the top 710A and bottom 710B halves are joined, the supplemental semi-cylindrical portion 713A of one half 710A is in registration with the supplemental semi-cylindrical portion of the other half such that cylindrical umbilical opening 713 is produced.

The top half 710A and the bottom half 710B each include a supplemental circular planar edge which, when the top 710A and the bottom halves are joined, is in registration with, is of equivalent shape and dimension to, and contacts the supplemental circular planar edge of the opposing half. In FIG. 81, this supplemental edge for half 710A is indicated by reference character 716A. When the top 710A and bottom 710B halves are joined, the supplemental planar edge 716A of one half 710A is in registration with the supplemental semi-cylindrical portion of the other half such that cylindrical umbilical opening 713 is produced.

The top half 710A and the bottom half 710B each include a supplemental semi-cylindrical casing portion which, when the top 710A and the bottom halves are joined, comprises one half of cylindrical casing 711. In FIG. 81, this supplemental semi-cylindrical casing portion is indicated by reference character 711A. In addition, each supplemental semi-cylindrical casing portion 711A includes a supplemental generally tapered semi-cylindrical housing detent (i.e., indented) portion which is shaped and dimensioned to receive and seat assembly 511. In FIG. 81, this housing detent portion is indicated by references character 511A. When the top 710A and bottom halves are joined, the supplemental semi-cylindrical housing portion of one half 710A is in registration with the supplemental semi-cylindrical housing portion of the other half 710B such that a housing opening is formed which contours to, encloses, and secures assembly 511 in place in said housing opening. Consequently, during manufacture of toy 710, the halves 710A, 710B are formed, one half of assembly 511 is seated in the housing detent portion 511A of one half 710A, and the remaining half 710B is fastened to half 710A such that the edge 716A of each half contacts and is in registration with the opposing edge of the other half (to form spherical toy 710) and such that the hollow housing portion 511A in one half 710A is in registration with the mirror image hollow housing portion of the other half 710B such that assembly 511 is completely enclosed by and secured in position by said housing portions 511A in the manner illustrated in FIG. 79.

When halves 710A and 710B are joined they preferably to form a unitary compressibly elastically deformable hollow thin-walled elastomer core sealingly circumscribing and including a center, including a wall less than about eight millimeters thick, and including points on the exterior at varying distances from the center. A fabric cover is, if desired, applied to all or to a desired portion of exterior surface 712. Adhesive can, if desired, be utilized to secure the fabric cover to exterior surface 712. The fabric cover has a selected thickness, the ratio of the thickness of the fabric cover to the thickness of the wall being in the range of 1:6 to 1:0.15. Heat and pressure can be applied to the top half 710A, the bottom half 710B, and the fabric cover to secure the cover to the exterior surface 712.

An alternate embodiment of the invention is illustrated in FIG. 82. FIG. 82 illustrates a squeaker assembly in which a squeaker is housed in a protective casing 718 that is formed within the spherical exterior wall of a hollow elastic, resilient ball 730 or within another hollow animal toy having an exterior wall of desired shape and dimension. The spherical wall includes spherical outer surface 731. Protective casing 718 and the squeaker are spaced apart from outer surface 731. Casing 718 houses assembly 511 earlier described herein. As noted, cylindrical squeaker unit 516 is housed in assembly 511. Consequently, in FIG. 82, squeaker unit 516 is spaced apart from outer surface 731, which makes it difficult for a dog or other animal to access squeaker unit 516. Umbilical opening 723 extends from outer surface 731 completely through the wall of toy 730. Secondary umbilical opening 724 extends from assembly 511 to the exterior of casing 718. Umbilical tube 722 interconnects and extends from opening 724 to opening 723. Openings 723 and 724 and tube 722 collectively form the umbilical assembly 721 which connects assembly 511 with the ambient air outside of ball 730. Umbilical assembly 721 enables air to flow through the umbilical assembly 721 to and from assembly 511. If necessary, a tertiary umbilical opening 720 can extend from assembly 511 through casing 718 to the hollow air-filled interior of ball 730 to put assembly 511 and the squeaker unit 716 therein in fluid communication with the interior of ball 710 so that air can flow from the exterior of ball 710 through umbilical assembly 721, through assembly 511 and into the interior of hollow ball 730, or vice-versa. As would be appreciated in the art, and as is the case with various other hollow toys described herein, the hollow toy in which casing 718 is utilized need not have a spherical shape, but can have any desired shape and dimension.

The location and orientation and shape and dimension of casing 718 with respect to the wall of a toy 730 can vary as desired. In one embodiment of the invention, casing 718 “floats” and is free to move about within toy 730. In another embodiment of the invention, casing 718 is maintained in fixed position inside toy 730 by, for example, a wall or rib 719 that is connected to the interior of the outer spherical wall of toy 730. Umbilical tube 722 can be substantially rigid, can be pliable, and/or can be elastic and resilient.

When protective casing 718 encloses assembly 511, casing 718 and assembly 511 provide, in essence, a double layer of protection for squeaker unit 516. As would be appreciated by those of skill in the art, assembly 511 need not be utilized, and squeaker unit 516 can simply be housed in casing 718 such that umbilical assembly 721—and if necessary, secondary opening 715—permit air to flow through squeaker unit 516.

In still another embodiment of the invention, both casing 718 and assembly 511 are dispensed with, and squeaker unit 516, or some other desired squeaker unit that produce sound with or without the flow of air therethrough, is connected directly to umbilical tube 722 such that ambient air flows through umbilical opening 723 and umbilical tube 722 directly into and through squeaker unit 516. Or, in the event casing 718 and assembly are both dispensed with, squeaker unit 516 can be positioned on the interior of toy 730 and connected directly to umbilical opening 723 such that ambient air can flow through umbilical opening 723 and directly into and through squeaker unit 516, or vice versa. In such embodiments of the invention described in this paragraph, the squeaker unit 516 is still positioned apart from the exterior surface 731 and is in the interior circumscribed by the spherically shaped exterior wall of toy 730.

Toys 710 and 730, as well as all other toys described herein, can be fabricated utilizing any of the methods of manufacture described herein, or by using any other desired method of manufacture. Toys 710 and 730, as well as all other toys described herein, can incorporate all or part of the structure of any of the other toys described herein.

The shape and dimension of umbilical opening 713, 175, 723, and 724 can vary as desired, as can that of tube 722. For example, opening 713 or 723 can comprise the mouth or nose of a toy animal constructed in accordance with the invention, while casing 711 or 718 is still located on the interior of the toy animal.

In still another embodiment of the invention, casing 711 or 718 is mounted on the exterior of a toy 710, 730.

As would be appreciated by those of skill in the art, squeaker unit 516 includes a hollow reed housing and a reed mounted inside said reed housing. In one embodiment of the invention, casing 711 or 718 or the hollow reed housing is comprised of a hard, rigid material such as a hard plastic or aluminum. In another embodiment of the invention, casing 711 or 718 or the hollow reed housing is comprised of a tough but somewhat resilient polymer. In a further embodiment of the invention, casing 711 or 718 or the hollow reed housing is comprised of a resilient, elastic material.
